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 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() or fclose() on the same stream or a call to exit() or abort().

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.

ERRORS

Refer to fputwc().

EXAMPLES

None.

APPLICATION USAGE

The fputws() function does not append a <newline>.

RATIONALE

None.

FUTURE DIRECTIONS

None.

CHANGE HISTORY

First released in Issue 4. Derived from the MSE working draft.

Issue 5

The Optional Header (OH) marking is removed from <stdio.h>.

Issue 6

Extensions beyond the ISO C standard are marked.

The fputws() prototype is updated for alignment with the ISO/IEC 9899:1999 standard.
