GETW

getw, putw ? input and output of words (ints)

#include <stdio.h>

int getw(FILE *stream);
int putw(int w, FILE *stream);

getw reads a word (that is, an int) from stream. It’s provided for compatibility with SVID. We recommend you use fread(3) instead.

putw writes the word w (that is, an int) to stream. It is provided for compatibility with SVID, but we recommend you use fwrite(3) instead.

Normally, getw returns the word read, and putw returns the word written. On error, they return EOF.

The value returned on error is also a legitimate data value. ferror(3) can be used to distinguish between the two cases.
