<h4>Description</h4>
<p>The <tt>f_gets()</tt> function is a wrapper function of <ahref="read.html"><tt>f_read()</tt></a> function. The read operation continues until a <tt>'\n'</tt> is stored, reached end of the file or the buffer is filled with <tt>len - 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, it returns a null pointer. The status of EOF and error can be examined with <tt>f_eof()</tt> and <tt>f_error()</tt> macros.</p>
<p>When FatFs is configured to Unicode API (<tt>_LFN_UNICODE == 1</tt>), data types on the srting fuctions, <tt>f_putc()</tt>, <tt>f_puts()</tt>, <tt>f_printf()</tt> and <tt>f_gets()</tt>, is also switched to Unicode. The character encoding on the file to be read/written via those functions is selected by <tt>_STRF_ENCODE</tt> option.</p>
