getw, putw - input and output of words (ints)
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
Normally, getw returns the word read, and putw
returns 0. 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
fread(3), fwrite(3), ferror(3),
