TRAD_SYNOPSIS
|
|
#include <wchar.h>
|
|
int fputws(<[ws]>, <[fp]>)

DESCRIPTION
|
|
<<fputws>> writes the wide character string at <[ws]> (but without the
|
|
trailing null) to the file or stream identified by <[fp]>.
|
|
|
|
<<_fputws_r>> is simply the reentrant version of <<fputws>> that takes
|
|
an additional reentrant struct pointer argument: <[ptr]>.
|
|
|
|
RETURNS
|
|
If successful, the result is a non-negative integer; otherwise, the result
|
|
is <<-1>> to indicate an error.
