SYNOPSIS
#include <wchar.h>
int fputws(
wchar_t *string,
FILE *stream);
PARAMETERS
string Points to a string to be written to output.
stream Points to the FILE structure of an open file.
DESCRIPTION
The fputws() function writes the wchar_t string pointed to by the string parameter to the output
stream. Each element of the string parameter is converted to the equivalent multibyte character.
In all other respects, fputws( ) functions like fputs().
The st_ctime and st_mtime fields of the file are marked for update between the successful exe-
cution of the fputws( ) function, and the next successful completion of a call to the fflush() or
fclose( ) function on the same stream, or a call to the exit() or abort() function.
RETURN VALUES
Upon successful completion, the fputws( ) function returns the number of characters written.
This function returns EOF on an error.
ERRORS
If any of the following conditions occur, the fputws() function sets errno to the corresponding
value.
[EAGAIN] The O_NONBLOCK flag is set for the file descriptor underlying stream and the
process would be delayed in the write operation.
[EBADF] The file descriptor underlying stream is not a valid file descriptor open for writ-
ing.
[EFBIG] An attempt was made to write to a file that exceeds the process’s file size limit or
the maximum file size.
[EINTR] The read operation was interrupted by a signal that was caught, and no data was
transferred.
[EIO] The implementation supports job control; the process is a member of a back-
ground process group attempting to write to its controlling terminal; TOSTOP is
set; the process is neither ignoring nor blocking SIGTTOU; and the process
group of the process is orphaned.
[ENOMEM] Insufficient storage space available.
