FPUTWS(3P)		   POSIX Programmer's Manual		    FPUTWS(3P)

       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
       implementation of this interface may differ (consult the	 corresponding
       Linux  manual page for details of Linux behavior), or the interface may
       not be implemented on Linux.

       fputws — put a wide-character string on a stream

       #include <stdio.h>
       #include <wchar.h>

       int fputws(const wchar_t *restrict ws, FILE *restrict stream);

       The functionality described on this reference page is aligned with  the
       ISO C  standard.	 Any  conflict between the requirements described here
       and the ISO C standard is unintentional. This  volume  of  POSIX.1‐2008
       defers to the ISO C standard.

       The  fputws()  function shall write a character string corresponding to
       the (null-terminated) wide-character string pointed to  by  ws  to  the
       stream  pointed to by stream.  No character corresponding to the termi‐
       nating null wide-character code shall be written.

       The last data modification and last file status	change	timestamps  of
       the file shall be marked for update between the successful execution of
       fputws() and the next successful completion of a call  to  fflush()  or
       fclose() on the same stream or a call to exit() or abort().

       Upon  successful	 completion, fputws() shall return a non-negative num‐
       ber. Otherwise, it shall return −1, set	an  error  indicator  for  the
       stream, and set errno to indicate the error.

       Refer to fputwc().

       The following sections are informative.


       The fputws() function does not append a <newline>.

       This  volume of POSIX.1‐2008 requires that successful completion simply
       return a non-negative integer. There are at least three known different
       implementation conventions for this requirement:

	*  Return a constant value.

	*  Return the last character written.

	*  Return  the	number of bytes written. Note that this implementation
	   convention cannot be adhered to for strings longer  than  {INT_MAX}
	   bytes as the value would not be representable in the return type of
	   the	function.  For	backwards-compatibility,  implementations  can
	   return  the	number	of bytes for strings of up to {INT_MAX} bytes,
	   and return {INT_MAX} for all longer strings.
