GETW(3) Linux Programmer's Manual GETW(3) NAME getw, putw - input and output of words (ints) SYNOPSIS #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: _SVID_SOURCE || _BSD_SOURCE || (_XOPEN_SOURCE && !(_POSIX_C_SOURCE >= 200112L || _XOPEN_SOURCE >= 600)) Before glibc 2.3.3: _SVID_SOURCE || _BSD_SOURCE || _XOPEN_SOURCE DESCRIPTION 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. RETURN VALUE Normally, getw() returns the word read, and putw() returns 0. On error, they return EOF. CONFORMING TO SVr4, SUSv2. Not present in POSIX.1-2001. BUGS The value returned on error is also a legitimate data value. ferror(3) can be used to distinguish between the two cases. SEE ALSO ferror(3), fread(3), fwrite(3), getc(3), putc(3) COLOPHON This page is part of release 3.74 of the Linux man-pages project.
