The ReleaseLight()
call releases the light
target if it was previously reserved for the client. Multiple lights can be
specified by using bitwise-or. If the client has not reserved any of the specified
lights, this method does nothing. Any reserved light targets that are released
and have no other suspended clients are reset to default state, which is either
lights ON or lights OFF, depending on the system inactivity time. The following
code snippet demonstrates how to release the reserved light targets:
iLight->ReleaseLight( CHWRMLight::EPrimaryDisplay | CHWRMLight::EPrimaryKeyboard );
