FUNCTION
|
|
<<getw>>---read a word (int)
|
|
|
|
INDEX
|
|
getw
|
|
|
|
SYNOPSIS
|
|
#include <stdio.h>
|
|
int getw(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>>. */
