View the official Windows Driver Kit DDI referenceNo description available.
This routine undoes the operation from PRM_LOCK_MODULE and allows the module to be updated. PRM_UNLOCK_MODULE should always be preceded by exactly one PRM_LOCK_MODULE call.
HandlerGuid [in]Supplies the GUID of the PRM handler whose module needs to be unlocked.
This method returns NTSTATUS which contains STATUS_SUCCESS if the call was successful. Otherwise, the method returns an appropriate error code.
PRM_UNLOCK_MODULE is not a system routine that can be called directly by name. This routine is callable only by pointer from the address returned in a PRM_INTERFACE structure. Drivers obtain the address of this routine by calling ExGetPrmInterface.
