getw—read a word (int) #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.
