getw, putw - input and output of words (ints)
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 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)
Normally, getw() returns the word read, and putw() returns 0. On
error, they return EOF.
SVr4, SUSv2. Not present in POSIX.1-2001.
The value returned on error is also a legitimate data value. ferror(3)
can be used to distinguish between the two cases.
ferror(3), fread(3), fwrite(3), getc(3), putc(3)
