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 POSIX.1-2008 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 last data modification and last file status change timestamps 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.
