NdisRawWritePortUchar macro (ndis.h)
NdisRawWritePortUchar writes a byte to an I/O port on the NIC.
Syntax
void NdisRawWritePortUchar(
[in] Port,
[in] Data
);
Parameters
[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.
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.
