FPUTWS(3) Library Functions Manual FPUTWS(3)

NAME

fputws — put a wide-character string on a stream

SYNOPSIS

#include <stdio.h>
#include <wchar.h>

int fputws(const wchar_t *restrict ws, FILE *restrict stream);

DESCRIPTION

[CX] The functionality described on this reference page is aligned with the ISO C standard. Any conflict between the requirements described here and the ISO C standard is unintentional. This volume of IEEE Std 1003.1-2001 (“POSIX.1”) defers to the ISO C standard.

The fputws () function shall write a character string corresponding to the (null-terminated) wide-character string pointed to by ws to the stream pointed to by stream. No character corresponding to the terminating null wide-character code shall be written.

[CX] The st_ctime and st_mtime fields of the file shall be marked for update between the successful execution of fputws () and the next successful completion of a call to fflush(3) or fclose(3) on the same stream or a call to exit(3) or abort(3).

RETURN VALUE

Upon successful completion, fputws () shall return a non-negative number. Otherwise, it shall return -1, set an error indicator for the stream, [CX] and set errno to indicate the error.
