IN ULONG Port,
OUT PUCHAR Buffer,
IN ULONG Length
);

NdisRawReadPortBufferUchar reads a specified number of bytes into a caller-supplied buffer.

Parameters

Port

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

Buffer

Points to a caller-allocated buffer, in resident memory, into which the bytes will be transferred from the NIC's port. The caller must allocate a buffer at least sizeof(Length).

Length

Specifies how many bytes to transfer from the NIC.

Comments

NdisRawReadPortBufferUchar reads each byte, one at a time, from the given I/O port into the given buffer.

Callers of NdisRawReadPortBufferUchar can run at any IRQL.
