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

PROLOG
       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.

NAME
       fgetws - get a wide-character string from a stream

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

       wchar_t *fgetws(wchar_t *restrict ws, int n,
	      FILE *restrict stream);

DESCRIPTION
       The fgetws() function shall read characters from	 the  stream,  convert
       these  to  the  corresponding  wide-character  codes, place them in the
       wchar_t array pointed to by ws, until n-1 characters  are  read,	 or  a
       <newline>  is read, converted, and transferred to ws, or an end-of-file
       condition is encountered. The wide-character string, ws, shall then  be
       terminated with a null wide-character code.

       If  an error occurs, the resulting value of the file position indicator
       for the stream is unspecified.

       The fgetws() function may mark the st_atime field of the	 file  associā€
       ated  with  stream  for	update. The st_atime field shall be marked for
       update by the first successful execution of fgetc(), fgets(), fgetwc(),
       fgetws(),  fread(),  fscanf(),  getc(),	getchar(),  gets(), or scanf()
       using stream that returns data not supplied by a prior call to ungetc()
       or ungetwc().

RETURN VALUE
       Upon successful completion, fgetws() shall return ws.  If the stream is
       at end-of-file, the end-of-file indicator for the stream shall  be  set
       and  fgetws()  shall return a null pointer. If a read error occurs, the
       error indicator for the stream shall be set, fgetws()  shall  return  a
       null pointer,  and shall set errno to indicate the error.

ERRORS
       Refer to fgetwc().
