View the official Windows Driver Kit DDI referenceNo description available.
NdisRawWritePortBufferUchar writes a specified number of bytes from a caller-supplied buffer to a given I/O port.
Port [in]Specifies the I/O port. This address falls in a range that was mapped during initialization with NdisMRegisterIoPortRange.
Buffer [in]Pointer to a caller-allocated resident buffer containing the bytes to be written.
Length [in]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.
