FGETWS(3)		   BSD Programmer's Manual		     FGETWS(3)

NAME
     fgetws - get a line of wide characters from a stream

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

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

DESCRIPTION
     The fgetws() function reads at most one less than the number of charac-
     ters specified by n from the given fp and stores them in the wide charac-
     ter string ws. Reading stops when a newline character is found, at end-
     of-file, or error. The newline, if any, is retained. If any characters
     are read and there is no error, a '\0' character is appended to end the
     string.

RETURN VALUES
     Upon successful completion, fgetws() returns ws. If end-of-file occurs
     before any characters are read, fgetws() returns NULL and the buffer con-
     tents remain unchanged. If an error occurs, fgetws() returns NULL and the
     buffer contents are indeterminate. The fgetws() function does not distin-
     guish between end-of-file and error, and callers must use feof(3) and
     ferror(3) to determine which occurred.

ERRORS
     [EBADF]	   The given fp argument is not a readable stream.

     [EILSEQ]	   The data obtained from the input stream does not form a
		   valid multibyte character.

     The function fgetws() may also fail and set errno for any of the errors
     specified for the routines fflush(3), fstat(2), read(2), or malloc(3).

SEE ALSO
     feof(3), ferror(3), fgets(3)

STANDARDS
     The fgetws() function conforms to IEEE Std 1003.1-2001 ("POSIX").
