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 x has been deprecated and is superseded by NDIS 6.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.
NdisReadPortBufferUlong is called by the miniport driver to read a specified number of ULONGs from a NIC into a buffer.
VOID NdisReadPortBufferUlong( _In_ NDIS_HANDLE NdisAdapterHandle, _In_ ULONG Port, _Out_ PULONG Buffer, _In_ ULONG Length );
- NdisAdapterHandle [in]
Specifies the handle that the NDIS interface library associates with the network interface card.
- Port [in]
Specifies the I/O port.
- Buffer [out]
Pointer to the caller-supplied buffer in which this function writes the ULONG values read from Port.
- Length [in]
Specifies the number of pieces of data to read from Port to Buffer.
NdisReadPortBufferUlong reads sequentially each ULONG from the port. It determines how the host accesses the I/O port and processes the read request accordingly.
|Not supported for NDIS 6.0 drivers in Windows Vista. Supported for NDIS 5.1 drivers (see NdisReadPortBufferUlong (NDIS 5.1)) in Windows XP.|
