The DefDriverProc function provides default processing for any messages not processed by an installable driver.
dwDriverIdentifier
Identifies an installable driver. This parameter must have been obtained by a previous call to the OpenDriver function.
hdrvr
Identifies the installable driver.
uMsg
Specifies the message to be processed.
lParam1
Specifies 32 bits of additional message-dependent information.
lParam2
Specifies 32 bits of additional message-dependent information.
The return value is nonzero if the function is successful. Otherwise, it is zero.
