<h4>Return Values</h4>
<p>When the function succeeded, <tt>Str</tt> will be returuned.</p>

<div class="para desc">
<h4>Description</h4>
<p>The f_gets() is a wrapper function of <a href="read.html">f_read()</a>. The read operation continues until a <tt>'\n'</tt> is stored, reached end of the file or the buffer is filled with <tt>Size - 1</tt> characters. The read string is terminated with a <tt>'\0'</tt>. When no character to read or any error occured during read operation, f_gets() returns a null pointer. The end of file and error status can be examined with <tt>f_eof()</tt> and <tt>f_error()</tt> macros.</p>
<p>When the FatFs is configured to Unicode API (<tt>_LFN_UNICODE == 1</tt>), the file is read in UTF-8 encoding and stored it to the buffer in UCS-2. If not the case, the file will be read in one byte per character without any code conversion.</p>
</div>


<div class="para comp">
<h4>QuickInfo</h4>
<p>Available when <tt>_USE_STRFUNC</tt> is 1 or 2. When it is set to 2, <tt>'\r'</tt>s contained in the file are stripped out.</p>
