fputws(3)               Library Functions Manual               fputws(3)

NAME

       fputws - write a wide-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 wide-character equivalent of the
       fputs(3) function.  It writes the wide-character string starting
       at ws, up to but not including the terminating null wide
       character (L'\0'), 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.

STANDARDS

       C11, POSIX.1-2008.

HISTORY

       POSIX.1-2001, 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 wide-character
       string ws.
