Writes an integer to a stream.
#include <stdio.h>
int _putw( int binint, FILE *stream );
| binint | Binary integer to be output | |
| stream | Pointer to FILE structure |
The _putw function writes a binary value of type int to the current position of stream. The _putw function does not affect the alignment of items in the stream, nor does it assume any special alignment.
The _putw function is provided primarily for compatibility with previous libraries. Note that portability problems may occur with _putw, since the size of an int and ordering of bytes within an int differ across systems.
The _putw function returns the value written. A return value of EOF may indicate an error. Since EOF is also a legitimate integer value, ferror should be used to verify an error.

Use _putw for compatibility with ANSI naming conventions of non-ANSI functions. Use putw and link with OLDNAMES.LIB for UNIX compatibility.
