COM_MESSAGE_PUMP(3)							 1						       COM_MESSAGE_PUMP(3)

com_message_pump - Process COM messages, sleeping for up to timeoutms milliseconds

SYNOPSIS
       bool com_message_pump ([int  $timeoutms])

DESCRIPTION
	This function will sleep for up to $timeoutms milliseconds, or until a message arrives in the queue.

	The  purpose  of this function is to route COM calls between apartments and handle various synchronization issues. This allows your script
       to wait efficiently for events to be triggered, while still handling other events or running other code in the background. You  should  use
       it in a loop, as demonstrated by the example in the com_event_sink(3) function, until you are finished using event bound COM objects.

PARAMETERS
	      o $timeoutms
		-  The	timeout,  in  milliseconds.  If you do not specify a value for $timeoutms, then 0 will be assumed. A 0 value means that no
		waiting will be performed; if there are messages pending they will be dispatched as before; if there are no messages pending,  the
		function will return FALSE immediately without sleeping.

RETURN VALUES
	If a message or messages arrives before the timeout, they will be dispatched, and the function will return TRUE. If the timeout occurs and
       no messages were processed, the return value will be FALSE.
