FUNCTION
<<getw>>---read a word (int)
INDEX
getw
ANSI_SYNOPSIS
#include <stdio.h>
int getw(FILE *<[fp]>);
TRAD_SYNOPSIS
#include <stdio.h>
int getw(<[fp]>)
FILE *<[fp]>;
DESCRIPTION
<<getw>> is a function, defined in <<stdio.h>>. You can use <<getw>>
to get the next word from the file or stream identified by <[fp]>. As
a side effect, <<getw>> advances the file's current position
indicator.
RETURNS The next word (read as an <<int>>), unless there is no more
data, or the host system reports a read error; in either of these
situations, <<getw>> returns <<EOF>>. Since <<EOF>> is a valid
<<int>>, you must use <<ferror>> or <<feof>> to distinguish these
situations.
PORTABILITY
<<getw>> is a remnant of K&R C, it is not part of any ISO C Standard.
<<fread>> should be used instead. In fact, this implementation of
<<getw>> is based upon <<fread>>.
Supporting OS subroutines required: <<fread>>. */
