NAME

fputws - write a wid-character string to a FILE stream

LIBRARY

Standard C library (libc,~-lc)

SYNOPSIS

#include <wchar.h>
int fputws(const wchar_t *restrict ws, FILE *restrict stream);

DESCRIPTION

The fputws() function is the wid-character equivalent of the fputs(3) function. It writes the wid-character string starting at ws, up to but not including the terminating null wide character (L[aq][rs]0[aq]), to stream. For a nonlocking counterpart, see unlocked_stdio(3).

RETURN VALUE

The fputws() function returns a nonnegative integer if the operation was successful, or -1 to indicate an error.

ATTRIBUTES

For an explanation of the terms used in this section, see attributes(7).

STANDARDS

C11, POSIX.-2008.

HISTORY

POSIX.-2001, C99.

NOTES

The behavior of fputws() depends on the LC_CTYPE category of the current locale. In the absence of additional information passed to the fopen(3) call, it is reasonable to expect that fputws() will actually write the multibyte string corresponding to the wid-character string ws.
