NdisRawReadPortBufferUchar macro (ndis.h)
NdisRawReadPortBufferUchar reads a specified number of bytes into a caller-supplied buffer.
Syntax
void NdisRawReadPortBufferUchar(
[in] Port,
[out] Buffer,
[in] Length
);
Parameters
[in] Port
Specifies the I/O port. This address falls in a range that was mapped during initialization with NdisMRegisterIoPortRange.
[out] Buffer
Pointer 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 ).
[in] Length

Return value

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