────────────────────────────────────────────────────────────────────────────
The putw function writes a binary value of type int to the current
position of the 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.
Return Value
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.
