FUNCTION

<>---read a word (int)

INDEX

	getw

ANSI_SYNOPSIS

	#include 

	int getw(FILE *<[fp]>);

TRAD_SYNOPSIS

	#include 

	int getw(<[fp]>)

	FILE *<[fp]>;

DESCRIPTION

<> is a function, defined in <>.  You can use <>

to get the next word from the file or stream identified by <[fp]>.  As

a side effect, <> advances the file's current position

indicator.

RETURNS

The next word (read as an <>), unless there is no more

data or the host system reports a read error; in either of these

situations, <> returns <>.  Since <> is a valid

<>, you must use <> or <> to distinguish these

situations.

PORTABILITY

<> is a remnant of K&R C; it is not part of any ISO C Standard.

<> should be used instead.  In fact, this implementation of

<> is based upon <>.

Supporting OS subroutines required: <>.  */
