DESCRIPTION
|
||
|
<<fputws>> writes the wide character string at <[ws]> (but without the
|
||
|
trailing null) to the file or stream identified by <[fp]>.
|
||
|
|
||
|
<<fputws_unlocked>> is a non-thread-safe version of <<fputws>>.
|
||
|
<<fputws_unlocked>> may only safely be used within a scope
|
||
|
protected by flockfile() (or ftrylockfile()) and funlockfile(). This
|
||
|
function may safely be used in a multi-threaded program if and only
|
||
|
if they are called while the invoking thread owns the (FILE *)
|
||
|
object, as is the case after a successful call to the flockfile() or
|
||
|
ftrylockfile() functions. If threads are disabled, then
|
||
|
<<fputws_unlocked>> is equivalent to <<fputws>>.
|
||
|
|
||
|
<<_fputws_r>> and <<_fputws_unlocked_r>> are simply reentrant versions of the
|
||
|
above that take 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.
|
||
|
|
||
|
PORTABILITY
|
||
|
<<fputws>> is required by C99 and POSIX.1-2001.
|
||
|
|
||
|
<<fputws_unlocked>> is a GNU extension.
