+<h3>Disk I/O Interface</h3>
+<p>Since the FatFs module is completely separated from disk I/O layer, it requires following functions at least to access the physical media. When O/S related feature is enabled, it will require process/memory functions in addition. However the low level disk I/O module is not a part of FatFs module so that it must be provided by user. The sample drivers are also available in the resources.</p>

+<h3>How to Port</h3>
+
+<h4>Basic considerations</h4>
+<p>The FatFs module is assuming following conditions on portability.</p>
+<ul>
+<li>ANSI C<br>
+The FatFs module is a middleware which is written in ANSI C (C89). There is no platform dependence, so long as the compiler is in compliance with ANSI C.</li>
+<li>Size of integer types<br>
+The FatFs module assumes that size of char/short/long are 8/16/32 bit and int is 16 or 32 bit. These correspondence are defined in integer.h. This will not be a problem on most compilers. When any conflict with existing definitions is occured, you must resolve it with care.</li>
+</ul>
+
+<h4>Which function is required?</h4>
+<p>You need to provide only low level disk I/O functions that required by FatFs module and nothing else. If a working disk module for the target is already existing, you need to write only glue functions to attach it to the FatFs module. If not, you need to port any other disk module or write it from scratch. All defined functions are not that always required. For example, disk write function is not required in read-only configuration. Following table shows which function is required depends on configuration options.</p>
+<table class="lst2">
+<tr><th>Function</th><th>Required when:</th><th>Note</th></tr>
+<tr><td>disk_initialize<br>disk_status<br>disk_read</td><td>Always</td><td rowspan="5">Disk I/O functions.<br>Samples available in ffsample.zip.<br>There are many implementations on the web.</td></tr>

+<h3>Long File Name</h3>
+<p>The FatFs module has started to support long file name (LFN) at revision 0.07. The two different file names, SFN and LFN, of a file is transparent in the file functions except for f_readdir function. To enable LFN feature, set <tt>_USE_LFN</tt> to 1, 2 or 3, and add a Unicode code conversion function <tt>ff_convert()</tt> and <tt>ff_wtoupper()</tt> to the project. The LFN feature requiers a certain working buffer in addition. The buffer size can be configured by <tt>_MAX_LFN</tt> corresponding to the available memory size. The size of long file name will reach up to 255 characters so that the <tt>_MAX_LFN</tt> should be set to 255 for full featured LFN operation. If the size of working buffer is insufficient for the given file name, the file function fails with <tt>FR_INVALID_NAME</tt>. When enable the LFN feature with re-entrant feature, <tt>_USE_LFN</tt> must be set to 2 or 3. In this case, the file function allocates the working buffer on the stack or heap. The working buffer occupies <tt>(_MAX_LFN + 1) * 2</tt> bytes.</p>
+<table class="lst2 rset">
+<caption>LFN cfg on ARM7</caption>
+<tr><th>Code page</th><th>Program size</th></tr>
+<tr><td>SBCS</td><td>+3.7K</td></tr>
+<tr><td>932(Shift-JIS)</td><td>+62K</td></tr>

+<tr><td>949(Korean)</td><td>+139K</td></tr>
+<tr><td>950(Big5)</td><td>+111K</td></tr>
+</table>
+<p>When the LFN feature is enabled, the module size will be increased depends on the selected code page. Right table shows how many bytes increased when LFN feature is enabled with some code pages. We are the East-Asians have tens of thousands of characters. Unfortunately, it requires a huge OEM-Unicode bidirectional conversion table and the module size will be drastically increased that shown in the table. As the result, the FatFs with LFN feature with DBCS will not able to be implemented to most 8-bit microcontrollers. <small>This is the reason why I had not been interested in implementing the LFN feature for a long time :-)</small></p>
+<p>Note that the LFN feature on the FAT file system is a patent of Microsoft Corporation. This is not the case on FAT32 but most FAT32 drivers include the LFN feature. FatFs can swich the LFN feature by configuration option. When enable LFN feature on the commercial products, a license from Microsoft may be required depends on the final destination.</p>
+</div>
+
+<div class="para" id="unicode">
+<h3>Unicode API</h3>
+<p>FatFs supports ANSI/OEM code set on the API in default but FatFs can also switch the code set to Unicode. For more information, refer to the description in the <a href="filename.html">file name</a>.</p>
+</div>
+
+<div class="para" id="reentrant">
+<h3>Re-entrancy</h3>
+<p>The file operations to the different volume is always re-entrant and can work simultaneously. The file operations to the same volume is not re-entrant but it can also be configured to thread-safe with <tt>_FS_REENTRANT</tt> option. In this case, also the OS dependent synchronization object control functions, ff_cre_syncobj, ff_del_syncobj, ff_req_grant and ff_rel_grant must be added to the project.</p>
+<p>When a file function is called while the volume is in use by any other task, the file function is suspended until that task leaves file function. If wait time exceeded a period defined by <tt>_TIMEOUT</tt>, the file function will abort with <tt>FR_TIMEOUT</tt>. The timeout feature might not be supported on some RTOS.</p>
+<p>There is an exception on f_mount and f_mkfs function. These functions are not re-entrant to the same volume. When use these functions, all other task must close the corresponding file on the volume and avoid to access the volume.</p>
+<p>Note that this section describes on the re-entrancy of the FatFs module itself but also the low level disk I/O layer must be re-entrant.</p>
+</div>
+
+<div class="para" id="dup">
+<h3>Duplicated File Access</h3>
+<p>FatFs module does not support the shareing controls of duplicated file access in default. It is permitted when open method to a file is only read mode. The duplicated open in write mode to a file is always prohibited and open file must not be renamed, deleted, or the FAT structure on the volume can be collapted.</p>
+<p>The file shareing control can also be available when <tt>_FS_SHARE</tt> is set to 1 or grater. The value specifies the number of files to manage simultaneously. In this case, if any open, rename or remove that violating the file shareing rule that described above is attempted, the file function will fail with <tt>FR_LOCKED</tt>. If number of open files gets larger than <tt>_FS_SHARE</tt>, the f_open function will fail with <tt>FR_TOO_MANY_OPEN_FILES</tt>.</p>
+</div>
+
+<div class="para" id="fs1">
+<h3>Performance Effective File Access</h3>
+<p>For good performance on reading/writing files on the small embedded system, application programmer should consider what process is done in the FatFs module. The file data on the disk is transferred in following sequence by f_read function.</p>
+<p>Figure 1. Sector miss-aligned read (short)<br>
+<img src="../img/f1.png" width="490" height="110" alt="">
+</p>
+<p>Figure 2. Sector miss-aligned read (long)<br>
+<img src="../img/f2.png" width="490" height="140" alt="">
+</p>
+<p>Figure 3. Sector aligned read<br>
+<img src="../img/f3.png" width="490" height="119" alt="">
+</p>
+<p>The file I/O buffer means a sector buffer to read/write a partial data on the sector. The sector buffer is either file private sector buffer on each file object or shared sector buffer on the file system object. The buffer configuration option <tt>_FS_TINY</tt> determins which sector buffer is used for the file data transfer. When tiny buffer (1) is selected, data memory consumption is reduced 512 bytes each file object. In this case, FatFs module uses only a sector buffer on the file system object for file data transfer and FAT/directory access. The disadvantage of the tiny buffer configuration is: the FAT data cached in the sector buffer will be lost by file data transfer and it must be reloaded at every cluster boundary. However it will be suitable for most application from view point of the decent performance and low memory comsumption.</p>
+<p>Figure 1 shows that partial sector data is transferred via the file I/O buffer. On long data transfer shown in Figure 2, middle of transfer data that covers one or more sector is transferred to application buffer directly. Figure 3 shows that the case of entier transfer data is aligned to the sector boundary. In this case, file I/O buffer is not used. On the direct transfer, the maximum extent of sectors are read with disk_read function at a time but the multi sector transfer never across the cluster boundary even if it is contiguous.</p>
+<p>Therefore taking effort to sector aligned read/write accesss avoids buffered data transfer and the read/write performance will be improved. Besides the effect, cached FAT data will not be flushed by file data transfer on the tiny configuration so that it can achieve same performance as non-tiny configuration with small memory footprint.</p>
+</div>
+
+<div class="para" id="fs2">
+<h3>Considerations on Flash Memory Media</h3>
+<p>To maximize the write performance of flash memory media, such as SDC and CFC, it must be controlled in consideration of its characteristitcs.</p>
+<h4>Using Mutiple-Sector Write</h4>
+<div class="rset">
+Figure 6. Comparison between Multiple/Single Sector Write<br>
+<img src="../img/f6.png" width="630" height="148" alt="fig.6">
+</div>
+<p>The write throughput of the flash memory media becomes the worst at single sector write and it increases proportional to the number of sectors per a write transaction. This effect more appers at more fast bus clock and its ratio often becomes grater than ten. The number of write transaction also affects the life time of the media. Therefore the application program should write the data in large block as possible. The ideal block size is cluster size or power of 2 bytes and the byte offset should be aligned to the block. Of course all layers between the application and the media must support multiple sector write feature, however most of open-source disk drivers lack it. Do not split a multiple sector write request into single sector writes or the write throughput gets poor. Note that FatFs module and its sample disk drivers supprt multiple sector read/write.</p>
+<h4>Forcing Memory Erase</h4>
+<p>When remove a file via f_remove function, the data clusters occupied by the file are marked 'free' on the FAT. But the data sectors containing the file data are not that applied any process so that the file data left occupies a part of the media as live blocks. If the file data is forced erased on removing the file, the number of free blocks on the media will be increased. This may skip internal block erase operation to the data block on next write. As the result the write performance might be improved. To enable this feature, set <tt>_USE_ERASE</tt> to 1. Note that this is a feature with expectation of internal process of the flash memory media. It may not always effective and f_remove function will take a time on removing a large file.</p>
+</div>
+
+<div class="para" id="critical">
+<h3>Critical Section</h3>
+<p>If a write operation to the FAT file system is interrupted due to any accidental failure, such as sudden blackout, incorrect disk removal and unrecoverable disk error, the FAT structure can be collapted. Following images shows the critical section on the FatFs application.</p>
+<div class="lset">
+Figure 4. Long critical section<br>
+<img src="../img/f4.png" width="320" height="436" alt="fig.4">
+</div>
+<div class="lset">
+Figure 5. Minimized critical section<br>
+<img src="../img/f5.png" width="320" height="436" alt="fig.5">
+</div>
+<br class="clr">
+<p>An interruption in the red section can cause a cross link; as a result, the object being changed may be lost. There is one or more possibility listed below when an interruption in the yellow section is occured.</p>
+<ul>
+<li>File data being rewrited is collapted.</li>
+<li>A file being appended returns initial state.</li>
+<li>A file created as new is gone.</li>
+<li>A file created as new or in overwritten remains with no content.</li>
+<li>Efficiency of disk use gets worse due to lost clusters.</li>
+</ul>
+<p>Each case does not affect the files that not in write mode open. To minimize risk of data loss, the critical section can be minimized like shown in Figure 5 by minimizing the time that file is opened in write mode or using f_sync function properly.</p>

+<h1>Path Names</h1>
+
+<div class="para" id="nam">
+<h3>Format of the path names</h3>
+<p>The path name format on the FatFs module is similer to the filename specs of DOS/Windos as follows:</p>
+<p><tt>"[drive#:][/]directory/file"</tt></p>
+<p>The FatFs module supports long file name (LFN) and 8.3 format file name (SFN). The LFN can be used when LFN feature is enabled <tt>(_USE_LFN &gt; 0)</tt>. The sub directories are separated with a \ or / in the same way as DOS/Windows API. Duplicated separators are skipped and ignored. Only a difference is that the logical drive is specified in a numeral with a colon. When the drive number is omitted, it is assumed as default drive (0 or current drive).</p>
+<p>Control characters (\0 to \x1F) are recognized as end of the path name. Leading/embedded spaces in the path name are valid as a part of the name on LFN configuration but they are recognized as end of the path name on non-LFN configuration. Trailing spaces and dots are ignored.</p>
+<p>In default configuration <tt>(_FS_RPATH == 0)</tt>, it does not have a concept of current directory like OS oriented file system. All objects on the volume are always specified in full path name that follows from the root directory. Dot directory names are not allowed. Heading separator is ignored and it can be exist or omitted. The default drive number is fixed to 0.</p>
+<p>When relative path feature is enabled <tt>(_FS_RPATH == 1)</tt>, specified path is followed from the root directory if a heading separator is exist. If not, it is followed from the current directory set with <a href="chdir.html">f_chdir</a> function. Dot names are also allowed for the path name. The default drive is the current drive set with <a href="chdrive.html">f_chdrive</a> function.</p>
+<table class="lst2">
+<tr><td>Path name</td><td>_FS_RPATH == 0</td><td>_FS_RPATH == 1</td></tr>
+<tr class="lst3"><td>file.txt</td><td>A file in the root directory of the drive 0</td><td>A file in the current directory of the current drive</td></tr>

+<div class="para" id="uni">
+<h3>Unicode API</h3>
+<p>The path names are input/output in either ANSI/OEM code (SBCS/DBCS) or Unicode depends on the configuration options. The type of arguments that specifies the file names are defined as <tt>TCHAR</tt> which is an alias of <tt>char</tt> in default. The code set of the file name string is the ANSI/OEM code set specifid by <tt>_CODE_PAGE</tt>. When <tt>_LFN_UNICODE</tt> is set to 1 under LFN configuration, the type of the <tt>TCHAR</tt> is switched to <tt>unsigned short</tt> (UCS-2 character) to support Unicode. In this case, the LFN feature is fully supported and the Unicode specific characters, such as ✝☪✡☸☭, can also be used for the path name. It also affects data types and encoding of the string I/O functions. To define literal strings, <tt>_T(s)</tt> and <tt>_TEXT(s)</tt> macro are available to select either ANSI/OEM or Unicode automatically. The code shown below is an example to define the literal strings.</p>
+<pre>
+ f_open(fp, "filename.txt", FA_READ);      <span class="c">/* ANSI/OEM only */</span>
+ f_open(fp, L"filename.txt", FA_READ);     <span class="c">/* Unicode only */</span>

+<h3>Correspondence between logical and physical drives</h3>
+<p>The FatFs module has work areas that called <em>file system object</em> for each volume (logical drive). In default, each logical drive is bound to the physical drive that has same drive number. It attempts to mount a volume as SFD format and first FDISK partition. When <tt>_MULTI_PARTITION &gt;= 1</tt> is specified in configuration option, each individual logical drive is bound to any physical drive/partition. In this case, a volume management table must be defined by user. It is used to resolve relationship between logical drives and partitions as follows:</p>
+<pre>
+Example: Logical drive 0-2 are assigned to three pri-partitions on the physical drive 0 (fixed disk)
+         Logical drive 3 is assigned to physical drive 1 (removable disk)
+
+PARTITION VolToPart[] = {
+    {0, 1},     <span class="c">/* Logical drive 0 ==> Physical drive 0, 1st partition */</span>
+    {0, 2},     <span class="c">/* Logical drive 1 ==> Physical drive 0, 2nd partition */</span>
+    {0, 3},     <span class="c">/* Logical drive 2 ==> Physical drive 0, 3rd partition */</span>
+    {1, 0}      <span class="c">/* Logical drive 3 ==> Physical drive 1 (auto detection) */</span>
+};
+</pre>
+<p>There are some considerations when use <tt>_MULTI_PARTITION</tt> configuration.</p>
+<ul>
+<li>Only four pri-partitions can be mounted. Extended partition is not supported.</li>
+<li>The physical drive that has two or more partitions must be non-removable class.</li>
+</ul>

+<h4>Description</h4>
+<p>The f_lseek function moves the file read/write pointer of an open file. The offset can be specified in only origin from top of the file. When an offset above the file size is specified in write mode, the file size is increased to the offset and the data in the expanded area is undefined. This is suitable to create a large file quickly, for fast write operation. After the f_lseek function succeeded, current read/write pointer (member <tt>fptr</tt> in the file object) should be checked in order to make sure the read/write pointer has been moved correctry. In case of the current read/write pointer is not the expected value, either of followings has been occured.</p>
+<ul>
+<li>End of file. The specified Offset was clipped at the file size because the file has been opened in read-only mode.</li>
+<li>Disk full. There is insufficient free space on the volume to expand the file size.</li>
+</ul>
+<p>Fast seek mode is enabled when <tt>_USE_FASTSEEK</tt> is set to 1 and the member <tt>cltbl</tt> in the file object is not NULL. This feature enables fast backward/long seek operations without FAT access by cluster link map table (CLMT) stored in the user defined table. It is also applied to f_read/f_write functions. In this mode, the file size cannot be increased by f_write/f_lseek functions.</p>
+<p>The CLMT must be created in the user defined DWORD array prior to use fast seek feature. To create the CLMT, set pointer to the DWORD array to the member <tt>cltbl</tt> in the file object, set the array size in unit of items into the first item and call the f_lseek function with <tt>Offset = CREATE_LINKMAP</tt>. After the function succeeded and CLMT is created, no FAT access is occured in subsequent f_read/f_write/f_lseek functions to the file. If the function failed with <tt>FR_NOT_ENOUGH_CORE</tt>, the given array size is insufficient for the file and the required items is returned into the first item of the array. The required array size is (number of fragments + 1) * 2 items. For example, when the file is fragmented in 5, 12 items will be required for the CLMT. </p>

When FDISK is specified, a primary partition occupies the entire disk space is created and then an FAT volume is created on the partition. When SFD is specified, the FAT volume starts from the first sector of the physical drive.</p>
+<p>If the logical drive is being bound to any partition (1-4) by multiple partition feature <tt>(_MULTI_PARTITION)</tt>, the FAT volume is created into the specified partition. In this case, the second argument is ignored. The physical drive must be partitioned with f_fdisk function or any other partitioning tool prior to use this function.</p>
+<p>Note that there are two partitioning rules, FDISK and SFD. The FDISK format is usually used for harddisk, MMC, SDC and CFC. It can divide a physical drive into one or more partitions with a partition table on the MBR. The SFD format is non-partitioned method. The FAT volume starts from the first sector on the physical drive without partition table. It is used for floppy disk, Microdrive, optical disk and super-floppy media.</p>
+<p>The FAT sub-type, FAT12/FAT16/FAT32, is determined by number of clusters on the volume and nothing else, according to the FAT specification issued by Microsoft. Thus which FAT sub-type is selected, is depends on the volume size and the specified cluster size. The cluster size affects performance of the file system and large cluster increases the performance.</p>

+<h4>Description</h4>
+<p>The f_readdir function reads directory entries in sequence. All items in the directory can be read by calling f_readdir function repeatedly. When all directory entries have been read and no item to read, the function returns a null string into <tt>f_name[]</tt> member without any error. When a null pointer is given to the <tt>FileInfo</tt>, the read index of the directory object will be rewinded.</p>
+<p>When LFN feature is enabled, <tt>lfname</tt> and <tt>lfsize</tt> in the file information structure must be initialized with valid value prior to use the f_readdir function. The <tt>lfname</tt> is a pointer to the string buffer to return the long file name. The <tt>lfsize</tt> is the size of the string buffer in unit of TCHAR. If either the size of read buffer or LFN working buffer is insufficient for the LFN or the object has no LFN, a null string will be returned to the LFN read buffer. If the LFN contains any charactrer that cannot be converted to OEM code, a null string will be returned but this is not the case on Unicode API configuration. When <tt>lfname</tt> is a NULL, nothing of the LFN is returned. When the object has no LFN, some small capitals can be contained in the SFN.</p>
+<p>When relative path feature is enabled <tt>(_FS_RPATH == 1)</tt>, "." and ".." entries are not filtered out and it will appear in the read entries.</p>

+<h4>Description</h4>
+<p>The f_sync function performs the same process as f_close function but the file is left opened and can continue read/write/seek operations to the file. This is suitable for the applications that open files for a long time in write mode, such as data logger. Performing f_sync of periodic or immediataly after f_write can minimize the risk of data loss due to a sudden blackout or an unintentional disk removal. However f_sync immediataly before f_close has no advantage because f_close performs f_sync in it. In other words, the differnce between those functions is that the file object is invalidated or not. </p>

+<h3>ポーティングの際に配慮すべきこと</h3>
+<h4>移植の際の前提条件</h4>
+<p>FatFsモジュールは移植性に関して次の点を前提としています。</p>
+<ul>
+<li>処理系はANSI C準拠であること。<br>
+FatFsモジュールはANSI C(C89)準拠で記述されているので、ANSI Cに準拠したまともなコンパイラなら特に処理系依存になる点はありません。</li>
+<li>char/short/longのサイズは、それぞれ8/16/32ビットで、intは16または32ビットであること。<br>
+サイズを明示する整数型が integer.h 内で定義されています。整数の型とサイズに関しては、まっとうな処理系なら問題ないはずですが、既存の定義と衝突した場合はユーザによって解決されなければなりません。</li>
+</ul>
+<h4>ユーザの作成する関数</h4>
+<p>必要なのは FatFsモジュールの要求するディスク関数を用意することだけで、それ以外にすることはありません。既に動作しているディスク関数があるならその APIを FatFsに合わせるだけで済みますが、無い場合はほかから移植するか、最初から書くかする必要があります。定義されている全ての関数が常に必要なわけではありません。例えば、リード・オンリー構成では書き込み系関数は必要ありません。次の表に構成オプションと要求される関数の対応を示します。</p>

+<h3>長いファイル名</h3>
+<p>FatFsモジュールはR0.07から長いファイル名(LFN)をサポートしました。ファイルに付けられた2つの異なる名前(短いファル名と長いファイル名)は、f_readdir関数を除くファイル操作関数において透過です。LFN機能を有効にするには、<tt>_USE_LFN</tt>を1,2または3に設定し、Unicode変換関数<tt>ff_convert(), ff_wtoupper()</tt>をプロジェクトに追加します。これらの関数は、<tt>option/cc*.c</tt>に含まれています。LFN機能は、加えてある程度のワーク・エリア(LFN操作バッファ)を必要とします。バッファ長は使用できるメモリに応じて<tt>_MAX_LFN</tt>オプションで構成されることができます。LFNの長さは最大255文字に達するので、LFN完全対応のためには<tt>_MAX_LFN</tt>は255に設定されるべきです。与えられたファイル名に対してバッファ長が不足した場合、ファイル関数は<tt>FR_INVALID_NAME</tt>で失敗します。</p>
+<p>何らかのリエントラント状態の下でLFN機能を使用する場合は、<tt>_USE_LFN</tt>は2または3に設定されなければなりません。この場合、ファイル関数はバッファをスタックやヒープに確保します。バッファ・サイズは、<tt>(_MAX_LFN + 1) * 2</tt>バイトになるので、スタック等のサイズはそれを考慮した十分なサイズでなければなりません。</p>

+<p>LFN機能の上手な使い方は、それを使わないということです。実際、組み込み用途ではLFN機能がどうしても必要になるということはほとんど無いはずです。LFNを有効にすると、選択されたコード・ページに応じてモジュール・サイズが増大されます。右の表に各コード・ページにおけるLFNを有効にしたときのモジュール・サイズの違いを示します。私たち日本人、中国人および韓国人は数万の文字を持ちます。不幸なことに、それは巨大なOEM－Unicode相互変換テーブルを要求し、モジュール・サイズは劇的に増大されます。その結果、LFNを有効にしたFatFsモジュールは、AVRを含む殆どの8ビット・マイコンにインプリメントされることができません。<small>これは長い間私がLFNをインプリメントすることに興味を持ってこなかった理由です。</small></p>
+<p>注: マイクロソフト社はFATファイル・システムについていくつかの特許を保有しています。いずれもLFNの実装に関するもので、LFN機能に対して$0.25/unitのライセンス料を要求しています。最近のFAT32ドライバの多くはLFN機能を含んでいるため、それらの使用に当たってライセンスが必要になりますが、FatFsではLFN機能の有効・無効を任意に構成できます。このため、商用製品でLFN機能を有効にするときは、最終仕向地によってはライセンスが必要かも知れません。</p>

+<h3>日本語ファイル名の大文字変換</h3>
+<p>CP932(Shift_JIS)でかつ非LFN構成のときは、拡張文字の小文字(2バイト英字・キリル文字・ギリシャ文字)に対して大文字変換を行わず、小文字のままSFNエントリに記録・検索されます(日本語MSDOS仕様)。このため、非LFN構成で全角小文字を含むファイルを作成すると、NT系Windowsでそのファイルを開けなくなります。LFN構成では大文字変換を行います(NT系Windows仕様)。</p>

+<div class="para" id="unicode">
+<h3>Unicode入出力への対応</h3>
+<p>ファイル関数のファイル名入出力はデフォルトでは ANSI/OEMコードですが、これをUnicodeに切り替えることもできます。Unicodeファイル名に関する詳細は、<a href="filename.html">ファイル名</a>を参照してください。</p>
+</div>
+
+<div class="para" id="reentrant">
+<h3>リエントランシー</h3>
+<p>互いに異なるボリュームに対するファイル操作はリエントラントで、常に同時平行に動作できます。同じボリュームに対してはデフォルトではリエントラントではありませんが、<tt>_FS_REENTRANT</tt>オプションでリエントラント(スレッド・セーフ)にすることはできます。この場合、OS依存の同期オブジェクト操作関数<tt>ff_cre_syncobj, ff_del_syncobj, ff_req_grant</tt> と <tt>ff_rel_grant</tt>もまたプロジェクトに追加されなければなりません。サンプル・コードと解説は<tt>option/syncobj.c</tt>にあります。</p>
+<p>この場合、あるタスクがボリュームを使用中に他のタスクからそのボリュームに対するファイル関数が呼び出されると、そのアクセスは先のタスクがファイル関数を抜けるまでブロックされます。もし、待ち時間が<tt>_TIMEOUT</tt>で指定された期間を越すと、その関数は<tt>FR_TIMEOUT</tt>でアボートします。いくつかのRTOSではタイムアウト機能はサポートされないかも知れません。</p>
+<p>ひとつの例外が<tt>f_mount()</tt>と<tt>f_mkfs()</tt>にあります。これらの関数は同じボリュームに対してリエントラントではありません。これらの関数を使用するときは、アプリケーション・レベルで排他制御しなければなりません。</p>

+<h3>多重ファイル・アクセス</h3>
+<p>FatFsモジュールではデフォルトでは多重アクセス制御機能をサポートしていません。ファイルに対する多重アクセスは、そのアクセス・モードによって制限されます。一つのファイルに対する多重オープンは、それらが全てリード・モードのときに限って許可されます。書き込みモードを含む多重オープン、また開かれているファイルに対するリネームや削除を行ってはなりません。さもないと、そのボリュームのFAT構造が破壊される可能性があります。</p>
+<p><tt>_FS_SHARE</tt>に1以上の値(値は同時に管理できるファイル数)をセットすることで多重アクセス制御機能が有効になり、ファイル単位の排他制御を自動で行うこともできます。この場合、上記のルールを破ったオープン・リネーム・削除を試みると、その関数は<tt>FR_LOCKED</tt>で失敗します。<tt>_FS_SHARE</tt>を越えた数のファイルをオープンしようとすると、<tt>FR_TOO_MANY_OPEN_FILES</tt>で失敗します。</p>

+<h3>効率的なファイル・アクセス</h3>
+<p>小規模な組込システムでのファイルの読み書きにおける効率の良いアクセスのため、アプリケーション・プログラマはFatFsモジュールの中でどのような処理が行われているか考慮すべきです。ストレージ上のデータはf_read関数により次のシーケンスで転送されます。</p>
+<p>図1. セクタ・ミスアラインド・リード (ショート)<br>
+<img src="../img/f1.png" width="490" height="110" alt="fig.1">
+</p>
+<p>図2. セクタ・ミスアラインド・リード (ロング)<br>
+<img src="../img/f2.png" width="490" height="140" alt="fig.2">
+</p>
+<p>図3. セクタ・アラインド・リード<br>
+<img src="../img/f3.png" width="490" height="119" alt="fig.3">
+</p>
+<p>ファイルI/Oバッファはセクタの一部のデータを読み書きするためのセクタ・バッファを意味します。セクタ・バッファは、それぞれのファイル・オブジェクト内のプライベート・セクタ・バッファまたはファイル・システム・オブジェクト内の共有セクタ・バッファのどちらかです。バッファ構成オプションの<tt>_FS_TINY</tt>は、データ転送にどちらを使うかを決定します。タイニー・バッファ(1)が選択されるとデータ・メモリの消費はそれぞれのファイル・オブジェクトで512バイト減少されます。この場合、FatFsモジュールはファイル・データの転送とFAT/ディレクトリ・アクセスにファイル・システム・オブジェクト内のセクタ・バッファだけを使用します。タイニー・バッファの欠点は、セクタ・バッファにキャッシュされたFATデータがファイル・データの転送により失われ、クラスタ境界の毎にリロードされなければならないことです。でも、悪くない性能と少ないメモリ消費の視点から多くのアプリケーションに適するでしょう。</p>
+<p>図1はセクタの一部のデータがファイルI/Oバッファを経由で転送されることを示します。図2に示される長いデータの転送では、転送データの中間の1セクタまたはそれ以上のセクタにまたがる転送データがアプリケーション・バッファに直接転送されています。図3は転送データ全体がセクタ境界にアライメントされている場合を示しています。この場合、ファイルI/Oバッファは使用されません。直接転送においては最大の範囲のセクタがdisk_read関数で一度に読み込まれますが、クラスタ境界を越えるマルチ・セクタ転送はそれが隣接であっても行われません。</p>
+<p>このように、セクタにアライメントしたファイルの読み書きへの配慮はバッファ経由のデータ転送を避け、読み書き性能は改善されるでしょう。その効果に加え、タイニー構成でキャッシュされたFATデータがファイル・データの転送によりフラッシュされず、非タイニー構成と同じ性能を小さなメモリ・フットプリントで達成できます。</p>

+<div class="para" id="fs2">
+<h3>フラッシュ・メモリの特性への配慮</h3>
+<p>HDDなどのディスク・メディアとは異なり、SDCやCFCなどのフラッシュ・メモリ・メディアの性能を引き出すには、その特性を意識した制御が必要になります。</p>
+<h4>マルチ・セクタ書き込み</h4>
+<div class="rset">
+図6. マルチ/シングル・セクタ・ライトの比較<br>
+<img src="../img/f6.png" width="630" height="148" alt="fig.6">
+</div>
+<p>フラッシュ・メモリ・メディアの書き込み速度はシングル・セクタ書き込みの時に最も低いものになり、一回のトランザクションで転送されるセクタ数が大きくなるほど書き込み速度は向上します。この効果はバス速度が高速になるほど顕著で、10倍以上の差が現れることも珍しくありません。書き込みトランザクションの回数はまた、メディアの寿命にも影響してきます。このため、アプリケーションはなるべく大きなブロック(クラスタ・サイズまたは2の累乗セクタ境界にアライメントした)で読み書きを行う必要があります。もちろん、アプリケーションからメディアに至る全てのレイヤがマルチ・セクタ転送に対応していないと意味がありません。残念ながら、既存のオープン・ソースのドライバの多くはマルチ・セクタ転送に未対応です。なお、FatFsモジュールおよびそれ用のサンプル・ドライバはマルチ・セクタ転送に対応しています。</p>
+<h4>明示的なメモリ消去</h4>
+<p>通常のファイル消去では、記録されたデータに対して何らかの制御が行われるわけではなく、単にFAT上に未使用クラスタとして記録されているだけです。このため、ファイルが消去されたあともそれらは有効なメモリ・ブロックとしてフラッシュ・メモリ上に残ります。そこで、ファイルを消去するとき、占有していたデータ・セクタを明示的に消去(つまり未使用ブロックにする)することにより、メディア内の空きブロックを増やすことができます。これにより、次にそのブロックに書き込むときの消去動作が無くなり、書き込み性能が向上する可能性があります。また、ウェアレベリングに使えるブロックが増え、メディアの耐久性も向上するかも知れません。この機能を有効にするには、構成オプションの<tt>_USE_ERASE</tt>に1を設定します。これはフラッシュ・メモリ・メディアの内部動作に期待した制御なので、効果があるとは限りません。また、ファイル消去の時間が延びることも考慮に入れるべきです。</p>

+<h3>クリチカル・セクション</h3>
+<p>ストレージ上のFAT構造を操作している途中で、停電、不正なメディアの取り外し、回復不能なデータ・エラー等の障害が発生すると、処理が中途半端な状態で中断され、その結果としてFAT構造が破壊される可能性があります。次にFatFsモジュールにおけるクリチカル・セクションと、その間の障害により起きうるエラーの状態を示します。</p>

+
+<body>
+<h1>パス名のフォーマット</h1>
+<div class="para" id="nam">
+<h3>ファイル・ディレクトリ名</h3>
+<p>FatFsモジュールでのファイル、ディレクトリ、ドライブの指定方法はDOS/Windows APIとほぼ同じです。パス名のフォーマットは次の通りです。</p>
+<p><tt>"[論理ドライブ番号:][/]ディレクトリ名/ファイル名"</tt></p>
+<p>FatFsモジュールは長いファイル名(LFN)および8.3形式ファイル名(SFN)に対応しています。LFNは、<tt>(_USE_LFN &gt; 0)</tt>のとき使用可能になります。ディレクトリ・セパレータにはDOS/Windows APIと同じく / と \ を使用します。連続したセパレータは無視され1個として扱われます。唯一の違いは、論理ドライブの指定だけです。論理ドライブ番号は、'0'～'9'の一文字の数字とコロンで指定し、省略した場合はデフォルト・ドライブ(0またはカレント・ドライブ)が選択されます。</p>
+<p>Nul文字と制御文字(\0～\x1F)は、パス名の終端として認識されます。パス名に先行あるいは中に含まれるスペースは、LFN構成では名前の一部として有効ですが、非LFN構成ではスペースはパス名の終端として認識されます。</p>
+<p>標準構成<tt>(_FS_RPATH == 0)</tt>のときは、全てのオブジェクトがルート・ディレクトリから辿る絶対パスで指定されます。OS指向なカレント・ディレクトリという概念は無く、またドット・ディレクトリ(&quot;.&quot;や&quot;..&quot;)は使用できません。パス名先頭のセパレータは無視されます。デフォルト・ドライブ番号は常に0になります。</p>
+<p>相対パスを有効<tt>(_FS_RPATH == 1)</tt>にしたときは、先行するセパレータの有無によって検索開始ディレクトリが変わり、セパレータがある場合はルート・ディレクトリから、無い場合は<a href="chdir.html">f_chdir関数</a>で設定されるカレント・ディレクトリからになります。またパス名にドット・ディレクトリが使用できます。デフォルト・ドライブ番号は<a href="chdrive.html">f_chdrive関数</a>で設定された値となります。</p>
+<table class="lst2">
+<tr><td>パス名</td><td>_FS_RPATH == 0</td><td>_FS_RPATH == 1</td></tr>
+<tr class="lst3"><td>file.txt</td><td>ドライブ0のルート・ディレクトリ下のファイル</td><td>カレント・ドライブのカレント・ディレクトリ下のファイル</td></tr>
+<tr><td>/file.txt</td><td>ドライブ0のルート・ディレクトリ下のファイル</td><td>カレント・ドライブのルート・ディレクトリ下のファイル</td></tr>

+<p><br></p>
+<div class="para" id="uni">
+<h3>Unicode API</h3>
+<p>ファイル関数の入出力のうちファイル名やパス名を指定する引数の型は、<tt>TCHAR</tt>で定義されていますが、これは<tt>char</tt>のエリアスになっています。そして、<tt>_CODE_PAGE</tt>で指定される ANSI/OEMコード(SBCSまたはDBCS)の文字列として扱われます。ファイル名入出力をUnicodeとする構成(LFN構成で、かつ<tt>_LFN_UNICODE</tt>を 1)にしたときは、<tt>TCHAR</tt>はワイド文字(<tt>unsigned short</tt>)に切り替わり、パス名にUnicodeを使用するようになります。これにより LFNフル対応となり、ANSI/OEMコードにない文字(たとえば ✝☪✡☸☭など)も使用できます。この設定は文字列入出力関数のデータ型とエンコーディングにも影響を与えます。リテラル文字列を定義するとき、次に示すように<tt>_T(s)</tt>および<tt>_TEXT(s)</tt>マクロを使ってANSI/OEMとUnicodeを自動切り替えすることができます。</p>
+<pre>
+ f_open(fp, "filename.txt", FA_READ);      <span class="c">/* ANSI/OEM専用コード */</span>
+ f_open(fp, L"filename.txt", FA_READ);     <span class="c">/* Unicode専用コード */</span>

+<h3>論理ドライブ(ボリューム)と物理ドライブ(ディスク装置)の対応</h3>
+<p>デフォルトの構成では、それぞれの論理ドライブは同じ番号の物理ドライブに1:1で結びつけられていて、SFDとしてまたは第1区画のボリュームがマウントされます。<tt>_MULTI_PARTITION</tt>に 1以上を指定すると、個々の論理ドライブに対して個別に物理ドライブ番号・区画を指定できるようになります。この構成では、論理ドライブと区画の対応を解決するためのテーブルを次に示すように定義する必要があります。</p>
+<pre>
+例:論理ドライブ0～2を物理ドライブ0(固定ディスク)の3つの基本区画に割り当て、
+   論理ドライブ3を物理ドライブ1(リムーバブル・ディスク)に割り当てる場合。
+

+    {1, 0}      <span class="c">/* 論理ドライブ 3 ==> 物理ドライブ 1, 自動検出 */</span>
+};
+</pre>
+<p>複数区画指定を使用する場合、次の点に注意しなければなりません。
+<ul>
+<li>マウント可能な区画は基本区画のみで、拡張区画内には対応しない。</li>
+<li>複数の区画を持つ物理ドライブは、非リムーバブルでなければならない。</li>

+<h4>解説</h4>
+<p>ファイルのリード/ライト・ポインタ(次に読み出し・書き込みされるバイトのオフセット)を移動します。オフセットの原点はファイル先頭です。書き込みモードでファイル・サイズより大きな値を指定すると、そこまでファイル・サイズが拡張され、拡張された部分のデータは未定義となります。データを遅延無く高速に書き込みたいときは、予めこの関数で必要なサイズまでファイル・サイズを拡張しておくと良いでしょう。f_lseek関数が正常終了したあとは、リード/ライト・ポインタが正しく移動したかチェックするべきです。リード/ライト・ポインタが指定より小さいときは、次の原因が考えられます。</p>
+<ul>
+<li>非書き込みモードまたは高速シーク・モードのため、ファイル・サイズでクリップされた。</li>
+<li>ファイル拡張中にディスクが満杯になった。</li>
+</ul>
+<p><tt>_USE_FASTSEEK</tt>に1が指定されていて、且つファイル・オブジェクトの<tt>cltbl</tt>メンバがNULL以外(ファイルを開いたときはNULL)のとき、高速シーク・モードになります。これはファイルのクラスタ配置情報(CLMT)をメモリ上に保持しておくことにより、FATにアクセスすることなく後方シークやロング・シークを高速に行う機能です。高速シーク・モードは、f_read/f_wtite関数にも適用されます。高速シーク・モードではf_wtite/f_lseek関数によるファイル・サイズの拡張はできません。</p>
+<p>高速シーク動作を行う前に、CLMTを作成しておく必要があります。これを作成するには、まず<tt>cltbl</tt>メンバにCLMT格納バッファ(DWORD配列)へのポインタをセットします。そして、配列の先頭要素にその配列の要素数を入れ、f_lseek関数を<tt>Offset</tt>に<tt>CREATE_LINKMAP</tt>を指定して実行します。関数が成功するとCLMTが作成され、以降のf_read/f_write/f_lseek関数ではFATへのアクセスは発生しません。<tt>FR_NOT_ENOUGH_CORE</tt>で失敗したときは配列サイズが不足で、先頭要素には実際に必要となる要素数が返されます。必要な要素数は、(ファイルの分割数 + 1) * 2 です。たとえば、ファイルが5つに分断されているときに必要な要素数は、12となります。</p>

+<h4>説明</h4>
+<p>f_mkfs関数は物理ドライブ上にFATボリュームを作成します。第二引数でFDISK形式が指定された場合は、物理ドライブ全体を占める基本区画(パーテーション)が作成され、その中にFATボリュームが作成されます。SFD形式では、FATボリュームは物理ドライブの先頭からベタで作成されます。</p>
+<p>マルチパーテーション機能<tt>(_MULTI_PARTITION)</tt>により、指定された論理ドライブが特定の区画(1～4)に結び付けられている場合、その区画の中にFATボリュームが作成されます。この場合、第二引数は無視され、また対応する物理ドライブはこれに先立ち、f_fdisk関数または他のツールで適切に区画設定されている必要があります。</p>
+<p>パーテーション形式には、FDISK形式とSFD形式の二通りありがあります。FDISK形式は、ハードディスク、MMC、SDC、CFCなどで使用されます。FDISK形式では一台の物理ドライブ上に一つまたは複数の区画を作成することができます。管理情報はMBR(物理ドライブの先頭セクタ)に記録されます。SFD形式は単に何の分割も行わない形式で、ボリュームは物理ドライブの先頭セクタから開始します。SFD形式は、フロッピーディスク、マイクロドライブ、光学ディスク、およびその他スーパーフロッピーメディアで使用されています。</p>
+<p>FATタイプ(FAT12/FAT16/FAT32)は、その論理ドライブ上の<em>クラスタ数によってのみ決定</em>される決まり[FAT仕様書より]になっていて、それ以外の要因はありません。したがって、どのFATタイプになるかはドライブ・サイズとクラスタ・サイズに依存します。クラスタ・サイズは大きくするほど性能が上がり、ディスク利用効率は落ちます。</p>
+<p>クラスタ数がFATタイプの境界に近くなるときは、FR_MKFS_ABORTEDで関数が失敗する可能性があります。</p>

+<h4>解説</h4>
+<p>FatFsモジュールではそれぞれの論理ドライブにファイル・システム・オブジェクトというワーク・エリアが必要です。この関数は論理ドライブにそのワーク・エリアを登録したり抹消したりします。何らかのファイル関数を使用する前にこの関数でその論理ドライブのワーク・エリアを与えておかなければなりません。<tt>FileSystemObject</tt>にヌル・ポインタを指定するとその論理ドライブのワーク・エリアの登録は抹消され、登録されていたワーク・エリアは破棄できます。操作対象のドライブに対して開かれているファイルやディレクトリがあった場合、それらは全て無効になります。</p>
+<p>この関数は、ドライブの状態に関わらず常に成功します。関数内では下位レイヤ(物理ドライブ)へのアクセスは発生せず、ワーク・エリアを初期化して内部配列にそのアドレスを登録するだけです。実際のマウント動作は、この関数の実行またはメディア交換発生の後、最初のファイル・アクセスのときに行われます。</p>
