SYNOPSIS
#include <stdio.h> #include <wchar.h>
int fputws(
const wchar_t *wcs,
FILE *stream );
LIBRARY
Standard C Library (libc)
STANDARDS
Interfaces documented on this reference page conform to industry stan‐
dards as follows:
fputws(): XSH5.0
Refer to the standards(5) reference page for more information about
industry standards and associated tags.
PARAMETERS
Points to a wide-character string to be written to output. Points to
the FILE structure of an open file.
DESCRIPTION
The fputws() function reads the wchar_t string pointed to by the wcs
parameter, converts each wide character to a multibyte character, and
writes the result to the output stream pointed to by the stream parame‐
ter. The function does not append a newline or a terminating null char‐
acter to the result.
The fputws() function parallels the fputs() function.
The st_ctime and st_mtime fields of the file are marked for update
between the successful execution 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
On successful completion, the fputws() function returns a non-negative
number to indicate the number of bytes written to the output stream.
Otherwise, the function returns -1, sets the error indicator for the
stream, and sets errno to indicate the error.
ERRORS
If any of the following conditions occur, the fputws() function sets
errno to the corresponding value: The O_NONBLOCK option is set for the
file descriptor underlying stream and the process would be delayed in
the write operation. The file descriptor underlying stream is not a
valid file descriptor open for writing. An attempt was made to write
to a file that exceeds the process's file-size limit or the maximum
file size.
The file is a regular file and an attempt was made to write at
or beyond the offset maximum associated with the corresponding
stream. The write operation was interrupted by a signal that
was caught, and no data was transferred. One of the following
errors was encountered: The process is a member of a background
process group attempting to write to its controlling terminal
and TOSTOP is set; the process is neither ignoring nor blocking
SIGTTOU and the process group of the process is orphaned. A
physical I/O error occurred. This condition is defined starting
with Issue 4 Version 2 and later revisions of the XSH specifica‐
tion. A wide character read from wcs does not correspond to a
valid multibyte character in the current locale. There was no
free space remaining on the device containing the file. An
attempt was made to write to a pipe or FIFO that is not open for
reading by any process. A SIGPIPE signal will also be sent to
the process.
