You -shouldn't need to load it yourself. It supplies the wait functions to -those modules. - -The synchronization modules are L<"Win32::ChangeNotify">, -L<"Win32::Event">, L<"Win32::Mutex">, & L<"Win32::Semaphore">. - -In addition, you can use C<wait_any> and C<wait_all> with -L<"Win32::Console"> and L<"Win32::Process"> objects. (However, those -modules do not export the wait functions; you must load one of the -synchronization modules (or just Win32::IPC)). - -=head2 Methods - -B<Win32::IPC> supplies one method to all synchronization objects. - -=over 4 - -=item $obj->wait([$timeout]) - -Waits for C<$obj> to become signalled. C<$timeout> is the maximum time -to wait (in milliseconds). If C<$timeout> is omitted, waits forever. -If C<$timeout> is 0, returns immediately. - -Returns: - - +1 The object is signalled - -1 The object is an abandoned mutex - 0 Timed out - undef An error occurred - -=back - -=head2 Functions - -=over 4 - -=item wait_any(@objects, [$timeout]) - -Waits for at least one of the C<@objects> to become signalled. -C<$timeout> is the maximum time to wait (in milliseconds). If -C<$timeout> is omitted, waits forever. If C<$timeout> is 0, returns -immediately. - -The return value indicates which object ended the wait: - - +N $object[N-1] is signalled - -N $object[N-1] is an abandoned mutex - 0 Timed out - undef An error occurred - -If more than one object became signalled, the one with the lowest -index is used. - -=item wait_all(@objects, [$timeout]) - -This is the same as C<wait_any>, but it waits for all the C<@objects> -to become signalled. The return value indicates the last object to -become signalled, and is negative if at least one of the C<@objects> -is an abandoned mutex. - -=back - -=head2 Deprecated Functions and Methods - -B<Win32::IPC> still supports the ActiveWare syntax, but its use is -deprecated. - -=over 4 - -=item INFINITE - -Constant value for an infinite timeout. Omit the C<$timeout> argument -instead. - -=item WaitForMultipleObjects(\@objects, $wait_all, $timeout) - -Warning: C<WaitForMultipleObjects> erases C<@objects>! -Use C<wait_all> or C<wait_any> instead. - -=item $obj->Wait($timeout) - -Similar to C<not $obj-E<gt>wait($timeout)>. - -=back - -=head1 INTERNALS - -The C<wait_any> and C<wait_all> functions support two kinds of -objects. Objects derived from C<Win32::IPC> are expected to consist -of a reference to a scalar containing the Win32 HANDLE as an IV. - -Other objects (for which C<UNIVERSAL::isa($object, "Win32::IPC")> is -false), are expected to implement a C<get_Win32_IPC_HANDLE> method. -When called in scalar context with no arguments, this method should -return a Win32 HANDLE (as an IV) suitable for passing to the Win32 -WaitForMultipleObjects API function. - -=head1 AUTHOR - -Christopher J.
