NdisRawReadPortBufferUchar (NDIS 5.1) function
Note NDIS 5. x has been deprecated and is superseded by NDIS 6. x. For new NDIS driver development, see Network Drivers Starting with Windows Vista. For information about porting NDIS 5. x drivers to NDIS 6. x, see Porting NDIS 5.x Drivers to NDIS 6.0.
NdisRawReadPortBufferUchar reads a specified number of bytes into a caller-supplied buffer.
VOID NdisRawReadPortBufferUchar( _In_ ULONG_PTR Port, _Out_ PUCHAR Buffer, _In_ ULONG Length );
- Port [in]
Specifies the I/O port. This address falls in a range that was mapped during initialization with NdisMRegisterIoPortRange.
- Buffer [out]
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).
- Length [in]
Specifies how many bytes to transfer from the NIC.
NdisRawReadPortBufferUchar reads each byte, one at a time, from the given I/O port into the given buffer.
