AtomicVirtualEvent

0 2.0

Locks out pen packets.

oid 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 );
