The Win32::IPC module provides synchronization for multiple objects created from
the Semaphore, Mutex, Process, and ChangeNotify classes.
wait method of this class is inherited by objects of the preceding
modules, as well as the functions
should not need to call Win32::IPC directly.
This method is used on any synchronization object. It waits for the object
to become signaled. It returns 1 if the object is signaled, -1 if the
object is an abandoned mutex, 0 if the call times out, and
undef on error.
timeout is the time to wait (in milliseconds). If no
specified, the method waits indefinitely.
Win32::IPC also defines the two functions
Waits for all the synchronization objects contained in
be signaled. The optional
timeout parameter is the same as described for
wait. The return value will be an integer that identifies the
last object to be signaled (the
nth object in the list, starting from
1). A negative integer (-
n) indicates that the
nth object was
an abandoned mutex. A return of 0 means that the function timed out; and
undef is returned on error.
