int _putw( int binint, FILE *fp );
.ixfunc2 '&StrIo' &func
.funcend
.desc begin
The &func function writes a binary value of type
.us int
to the current position of the stream
.arg fp.
&func does not affect the alignment of items in the stream, nor does
it assume any special alignment.
.np
&func is provided primarily for compatibility with previous libraries.
Portability problems may occur with &func because the size of an
.us int
and the ordering of bytes within an
.us int
differ across systems.
.desc end
.return begin
The &func function returns the value written or, if a write error
occurs, the error indicator is set and &func returns
.kw EOF.
Since
.kw EOF
is a legitimate value to write to
.arg fp,
use
.kw ferror
to verify that an error has occurred.
