chr

A character to write.
+
fp
+
Pointer to the open file object structuer.

+

Description

+

When FatFs is configured for Unicode API (FF_LFN_UNICODE >= 1), character encoding on the string fuctions, f_putc, f_puts, f_printf and f_gets function, is also switched to Unicode. The character encoding on the file to be read/written via those functions is selected by FF_STRF_ENCODE. The Unicode characters in multiple encoding unit, such as surrogate pair and multi-byte sequence, cannot be written with this function.

+
+ +
+

QuickInfo

+

This is a wrapper function of f_write function. Available when FF_FS_READONLY == 0 and FF_USE_STRFUNC >= 1. When FF_USE_STRFUNC == 2, a '\n' is output as '\r'+'\n'.
