NdisRawWritePortUchar macro (ndis.h)

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

Syntax

void NdisRawWritePortUchar(
  [in]  Port,
  [in]  Data
);

[in] Port

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

[in] Data

Specifies the byte to be written.

None

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.
