fputwc, putwc - write a wide character to a FILE stream
#include <stdio.h> #include <wchar.h> wint_t fputwc(wchar_t wc, FILE *stream); wint_t putwc(wchar_t wc, FILE *stream);
The fputwc() function is the wide-character equivalent of the fputc(3) function. It writes the wide character
ferror(stream) becomes true, it returns WEOF. If a wide-character conversion error occurs, it sets

For nonlocking counterparts, see unlocked_stdio(3).
