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

getw()  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.

       Standard C library (libc, -lc)

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

       Normally, getw() returns the word read, and putw() returns 0.  On error, they return EOF.
