NAME
fputwc - write a wide character to a FILE streamSYNOPSIS
#include <stdio.h>
#include <wchar.h> wint_t fputwc(wchar_t wc, FILE *stream); wint_t putwc(wchar_t wc, FILE *stream);
DESCRIPTION
The fputwc function is the wide-character equivalent of the fputc function. It writes the wide character wc to stream. If ferror(stream) becomes true, it returns WEOF. If a wide character conversion error occurs, it sets errno to EILSEQ and returns WEOF. Otherwise it returns wc.The putwc function or macro functions identically to fputwc. It may be implemented as a macro, and may evaluate its argument more than once. There is no reason ever to use it.
For non-locking counterparts, see unlocked_stdio(3).
RETURN VALUE
The fputwc function returns wc if no error occurred, or WEOF to indicate an error.ERRORS
Apart from the usual ones, there is- EILSEQ
- Conversion of wc to the stream's encoding fails.
