putw() -- STDIO Function (libc)

Write word into stream
#include <stdio.h>
int putw(word, fp)
int word; FILE *fp;

putw() writes word into the file stream to which fp points.

putw() differs  from the  related routine putc()  in that putw()  writes an
int, whereas putc() writes a char that is promoted to an int.

By  default, putw()  returns the  value  written.  If  an error  occurs, it
returns EOF.  You may need to  call ferror() to distinguish this value from
a genuine end-of-file flag.

Notes

Because putw() is  implemented as a macro as well  as a function, arguments
with side effects may not work  as expected.  The bytes of word are written
in the natural byte order of the machine.
