NAMEgetw, putw - input and output of words (ints)
#include <stdio.h> int getw(FILE *stream); int putw(int w, FILE *stream);
DESCRIPTIONgetw() reads a word (that is, an int) from stream. It's provided for compatibility with SVr4. We recommend you use fread(3) instead.
putw() writes the word w (that is, an int) to stream. It is provided for compatibility with SVr4, but we recommend you use fwrite(3) instead.
RETURN VALUENormally, getw() returns the word read, and putw() returns 0. On error, they return EOF.
CONFORMING TOSVr4, SUSv2. Not present in POSIX.1-2001.
BUGSThe value returned on error is also a legitimate data value. ferror(3) can be used to distinguish between the two cases.
