This function is called to release any resources that may have been allocated
by the PSD_INSTALL function. A PSD is never de-installed after its Init
routine is called.
Mode
Called in Init
Mode; may be called in Kernel Mode.
Entry
None.
Exit
NO_ERROR
if the PSD DeInstalled succesfully.
-1
if the PSD didn't DeInstall.
Notes
This function may be called after OS/2 is finished
with initialization by the DosTestPSD API; therefore, the PSD developer
must be careful not to use any init mode only PSDHelp's in this function.
