AtomicVirtualEvent
- 0 2.0
Locks out pen packets.
AtomicVirtualEvent( BOOL fBegin )
Parameters
fBegin
Flag for beginning or ending lockout. TRUE begins lockout, FALSE ends it.
Return Value
This function does not return a value.
Comments
AtomicVirtualEvent is used by the Pen Palette or a similar virtual-keyboard program to lock out
pen packets while the application is posting simulated key or mouse events.
Calling AtomicVirtualEvent with a TRUE value blocks input from physical devices until they are freed
with a call specifying FALSE. Applications should end the lockout as quickly as
possible.
An interruptable thread should not call AtomicVirtualEvent.
Example
The following code fragment posts a mouse click:
AtomicVirtualEvent( TRUE );
PostVirtualMouseEvent( VWM_MOUSELEFTDOWN, xPos, yPos );
PostVirtualMouseEvent( VWM_MOUSEMOVE, xPos, yPos );
PostVirtualMouseEvent( VWM_MOUSELEFTUP, xPos, yPos );
AtomicVirtualEvent( FALSE );
