PMIREQUEST_UNLOADPMIFILE - Syntax

Description: 

PMIREQUEST_UNLOADPMIFILE unloads the specified .PMI file. A .PMI file 
needs to be unloaded the same number of times it is loaded before all of 
its resources are freed. A .PMI file is loaded per driver-not per process. 
For example, a display driver, base video handler, and video configurator 
may all load the same .PMI file, which constitutes three users of the PMI 
subsystem. Before the PMI subsystem can be unloaded, 
PMIREQUEST_UNLOADPMIFILE must be invoked three times before the file is 
unloaded.
