NdisWriteRegisterUlong

VOID
   NdisWriteRegisterUlong(
       IN PULONG Register,
       IN ULONG Data
       );

NdisWriteRegisterUlong is called by the NIC driver to write a ULONG to a memory-mapped device register.

Parameters

Register

Points to the memory-mapped register. This virtual address must fall within a range returned by an initialization-time call to NdisMMapIoSpace.

Data

Specifies the caller-supplied ULONG that this function transfers to the Register.

Comments

If a driver calls this function, its NIC’s device registers must be mapped to noncached memory during driver initialization.

Callers of NdisWriteRegisterUlong can be running at any IRQL.
