NAME

6       getw, putw - input and output of words (ints)
7

SYNOPSIS

9       #include <stdio.h>
10
11       int getw(FILE *stream);
12
13       int putw(int w, FILE *stream);
14
15   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
16
17       getw(), putw():
18           Since glibc 2.3.3:
19               _XOPEN_SOURCE && ! (_POSIX_C_SOURCE >= 200112L)
20                   || /* Glibc since 2.19: */ _DEFAULT_SOURCE
21                   || /* Glibc versions <= 2.19: */ _BSD_SOURCE ||
22               _SVID_SOURCE
23           Before glibc 2.3.3:
24               _SVID_SOURCE || _BSD_SOURCE || _XOPEN_SOURCE

DESCRIPTION

27       getw() reads a word (that is, an int) from stream.  It's  provided  for
28       compatibility with SVr4.  We recommend you use fread(3) instead.
29
30       putw()  writes  the word w (that is, an int) to stream.  It is provided
31       for compatibility  with  SVr4,  but  we  recommend  you  use  fwrite(3)
32       instead.
33

RETURN VALUE

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

CONFORMING TO

48       SVr4, SUSv2.  Not present in POSIX.1.

BUGS

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