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>>. */ #if defined(LIBC_SCCS) && !defined(lint) static char sccsid[] = "%W% (Berkeley) %G%"; #endif /* LIBC_SCCS and not lint */ #include <_ansi.h> #include <stdio.h> int _DEFUN(getw, (fp), register FILE *fp) { int result; if (fread ((char*)&result, sizeof (result), 1, fp) != 1) return EOF; return result; }
