Thanks for the information... but is there any way by which i can trigger an event (or any other form of trigger mechanism) from the WakeupHandlerProc (after which the handler would return immediately and safely) and handle that event in some other function of the shared library?

You may invoke other routines in your shared library from that callback, provided they follow the same restrictions.... just be sure to pass a reference to your shared library globals (or some other state/context information that allows you to retrieve your shared library reference number, among other things) when setting up the wake up handler. > > Regards, > > Jim Schram > Palm Incorporated > Partner Engineering > > > -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/tech/support/forums/
