getw(3)                 Library Functions Manual                 getw(3)

ИМЯ

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

БИБЛИОТЕКА

       Standard C library (libc, -lc)

СИНТАКСИС

       #include <stdio.h>

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

   Feature Test Macro Requirements for glibc (see
   feature_test_macros(7)):

       getw(), putw():
           Since glibc 2.3.3:
               _XOPEN_SOURCE && ! (_POSIX_C_SOURCE >= 200112L)
                   || /* glibc >= 2.19: */ _DEFAULT_SOURCE
                   || /* glibc <= 2.19: */ _BSD_SOURCE || _SVID_SOURCE
           Before glibc 2.3.3:
               _SVID_SOURCE || _BSD_SOURCE || _XOPEN_SOURCE

ОПИСАНИЕ

       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.

ЗНАЧЕНИЕ, ВОЗВРАЩАЕМОЕ ФУНКЦИЕЙ

       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 cases.
