NAME

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

LIBRARY

     Standard C Library (libc, -lc)

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 characters specified by n from the given fp and stores them in the wide-char-
     acter string ws.  Reading stops when a newline character is found, at end-of-file or error.  The newline, if any, is retained.  If any char-
     acters are read and there is no error, a '' 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
     contents remain unchanged.  If an error occurs, fgetws() returns NULL and the buffer contents are indeterminate.  The fgetws() function does
     not distinguish 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.1'').

NAME

     fgetws, fgetws_l -- get a line of wide characters from a stream

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

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

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

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

     wchar_t *
     fgetws_l(wchar_t *restrict ws, int n, FILE *restrict stream, locale_t loc);

DESCRIPTION

     The fgetws() function reads at most one less than the number of characters specified by n from the given stream and stores them in the wide
     character 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 '' character is appended to end the string.

     While the fgetws() function uses the current locale, the fgetws_l() function may be passed a locale directly. See xlocale(3) for more infor-
     mation.

RETURN VALUES

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

ERRORS

     The fgetws() function will fail if:

     [EBADF]		The given stream 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), xlocale(3)

STANDARDS

     The fgetws() function conforms to IEEE Std 1003.1-2001 (``POSIX.1'').
