| 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>>. */ |
