PRM_UNLOCK_MODULE callback function (prminterface.h)
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.
Syntax
PRM_UNLOCK_MODULE PrmUnlockModule;
NTSTATUS PrmUnlockModule(
[in] LPGUID HandlerGuid
)
{...}
Parameters
[in] HandlerGuid
Supplies the GUID of the PRM handler whose module needs to be unlocked.
Return value
This method returns NTSTATUS which contains STATUS_SUCCESS if the call was successful. Otherwise, the method returns an appropriate error code.
Remarks
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.
