putw()

write word to stream 

Function


SYNOPSIS

#include <stdio.h>

int putw(int w, FILE *stream);


DESCRIPTION

The putw() function writes a binary integer to output stream stream in the native format of the local system and advances the file position accordingly. The function does not assume or perform any address alignment at the destination.

This is a legacy function, inherently non-portable.

EACCES 

Another process has the file locked.

EBADF
