PUTWC(3) Library Functions Manual PUTWC(3) NAME fputwc, putwc, putwchar - output a wide character to a stream LIBRARY Standard C Library (libc, -lc) SYNOPSIS #include #include wint_t fputwc(wchar_t wc, FILE *stream); wint_t putwc(wchar_t wc, FILE *stream); wint_t putwchar(wchar_t wc); DESCRIPTION The fputwc() function writes the wide character wc to the output stream pointed to by stream. The putwc() function acts essentially identically to fputwc(). The putwchar() function is identical to putwc() with an output stream of stdout. Extended locale versions of these functions are documented in putwc_l(3). See xlocale(3) for more information. RETURN VALUES The fputwc(), putwc(), and putwchar() functions return the wide character written. If an error occurs, the value WEOF is returned. SEE ALSO ferror(3), fopen(3), getwc(3), putc(3), putwc_l(3), stdio(3) STANDARDS The fputwc(), putwc(), and putwchar() functions conform to ISO/IEC 9899:1999 ("ISO C99"). macOS 26.6 March 3, 2004 macOS 26.6
