NdisRawWritePortUchar function

NdisRawWritePortUchar writes a byte to an I/O port on the NIC.

Syntax


VOID NdisRawWritePortUchar(
  _In_  ULONG_PTR Port,
  _In_  UCHAR Data
);

Parameters

Port [in]

Specifies the I/O port. This address falls in a range that was mapped during initialization with NdisMRegisterIoPortRange.

Data [in]

Specifies the byte to be written.

Return value

None

Remarks

NdisRawWritePortUchar runs fast because it need not map a bus-relative I/O port address onto a host-dependent logical port address at every call.

Requirements
