<h4>Return Value</h4>
|

<p>When the function succeeded, it returns number of characters written. When the write operation is aborted due to disk full or any error, an <tt>EOF (-1)</tt> will be returned.</p>
|

<p>When FatFs is configured to Unicode API (<tt>FF_LFN_UNICODE == 1</tt>), character encoding on the srting fuctions, <tt>f_putc</tt>, <tt>f_puts</tt>, <tt>f_printf</tt> and <tt>f_gets</tt> function, is also switched to Unicode. The character encoding on the file to be read/written via those functions is selected by <tt>FF_STRF_ENCODE</tt> option.</p>
