NdisRawWritePortBufferUchar writes a specified number of bytes from a caller-supplied buffer to a given I/O port.
void NdisRawWritePortBufferUchar( Port, Buffer, Length );
Specifies the I/O port. This address falls in a range that was mapped during initialization with NdisMRegisterIoPortRange.
Pointer to a caller-allocated resident buffer containing the bytes to be written.
Specifies the number of bytes to write to the I/O port.
A miniport driver calls NdisRawWritePortBufferUchar to transfer a sequence of bytes, one at a time, to a NIC.
NdisRawWritePortBufferUchar runs fast because it need not map a bus-relative port address onto a host-dependent logical port address at every call.
