fputws(3)
NAME
  fputws - Writes a wide-character string to a stream

LIBRARY
  Standard C Library (libc.so, libc.a)

SYNOPSIS
  #include <wchar.h>

  int fputws(
	  wchar_t *wcs,
	  FILE *stream);

  Application developers may want to specify an #include statement for
  <stdio.h> before the one for <wchar.h> if programs are being developed for
  multiple platforms. The additional #include statement is not required on
  DIGITAL UNIX systems or by ISO or X/Open standards, but may be required on
  other vendors' systems that conform to these standards.

STANDARDS
  Interfaces documented on this reference page conform to industry standards
  as follows:

  fputws(): XPG4, XPG4-UNIX

  Refer to the standards(5) reference page for more information about
  industry standards and associated tags.

PARAMETERS
  wcs Points to a wide-character string to be written to output.

  stream
      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 parameter.
  The function does not append a newline or a terminating null character 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:

  [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 writing.

  [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 write operation was interrupted by a signal that was caught, and
	 no data was transferred.

  [EIO]	 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.

	   ·
	   [XPG4-UNIX]	A physical I/O error occurred.

  [EILSEQ]
	 A wide character read from wcs does not correspond to a valid
	 multibyte character in the current locale.

  [ENOSPC]
	 There was no free space remaining on the device containing the file.

  [EPIPE]
	 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.
