VPEND_PENPLAYSTART

Sets up the virtual pen driver to replace the current stream of pen packets from the tablet with pen packets stored in an array of pen packets.

• DRV_SUCCESS or DRV_FAILURE if the virtual pen driver is already in playback mode or the tablet interrupts cannot be enabled.

lParam1

Pointer to a DWORD to receive a time stamp when play stops.

lParam2

Set to either PLAY_VERSION_10_DATA or PLAY_VERSION_20_DATA, which indicates the size and structure of the pen packets that are to be played back.

The VPEND_PENPLAYSTART message handler saves the two parameter values in global variables, sets a global variable that indicates the virtual pen driver is in playback mode, and then calls cOEM_API_Proc with a message that turns on tablet interrupts so the stream of pen packets from the tablet continues to flow.
