Init_RegisterSG rule (ndis)

The Init_RegisterSG rule specifies that the registration of the scatter-gather list (SG), which usually happens during initialization, must be undone if something goes wrong in the initialization process or during the halting of the miniport driver.

If NdisMRegisterScatterGatherDma is called at least one time during MiniportInitializeEx, the NdisMDeregisterScatterGatherDma function should be called at least one time in MiniportHaltEx.

Driver model: NDIS

How to test

At compile time
Run Static Driver Verifier and specify the Init_RegisterSG rule. Use the following steps to run an analysis of your code: Prepare your code (use role type declarations). Run Static Driver Verifier. View and analyze the results. For more information, see Using Static Driver Verifier to Find Defects in Drivers.
