This function is called by the miniport driver to read a specified number of UCHARs from a network adapter into a buffer.

Syntax

VOID
  NdisReadPortBufferUchar(
    IN NDIS_HANDLE  NdisAdapterHandle,
    IN ULONG  Port,
    OUT PUCHAR  Buffer,
    IN ULONG  Length
    );

Parameters

  • NdisAdapterHandle
    Specifies the handle that the NDIS interface library associates with the network interface card.

  • Buffer
    Pointer to the caller-supplied buffer in which this function writes the UCHAR values read from Port.
  • Length
    Specifies the number of pieces of data to read from Port to Buffer.
