NDIS I/O Port Raw Interface (Compact 2013)

3/26/2014

This section discusses the NDIS I/O port raw interfaces.

NdisRawReadPortXxx reads a single piece of data from an I/O port.

• NdisRawReadPortUchar
  Reads a byte from a given I/O port on the network adapter.

• NdisRawReadPortUlong
  Reads a ULONG value from a given I/O port on the network adapter.

• NdisRawReadPortUshort
  Reads a USHORT value from a given I/O port on the network adapter.

NdisRawReadPortBufferXxx reads a buffer of data a piece at a time from an I/O port. Specific functions include the following:

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

• NdisRawReadPortBufferUlong
  Reads a specified number of ULONGs into a caller-supplied buffer.

• NdisRawReadPortBufferUshort
  Reads a specified number of USHORTs into a caller-supplied buffer.

NdisRawWritePortXxx writes a single piece of data to an I/O port. Specific functions include the following:

• NdisRawWritePortUchar
  Writes a byte to an I/O port on the network adapter.

• NdisRawWritePortUlong
  Writes a ULONG value to an I/O port on the network adapter.

• NdisRawWritePortUshort
  Writes a USHORT value to an I/O port on the network adapter.

NdisRawWritePortBufferXxx writes a buffer of data to I/O port. Specific functions include the following:

• NdisRawWritePortBufferUchar
  Writes a specified number of bytes from a caller-supplied buffer to a given I/O port.

• NdisRawWritePortBufferUlong
  Writes a specified number of ULONG values from a caller-supplied buffer to a given I/O port.

• NdisRawWritePortBufferUshort
  Writes a specified number of USHORT values from a caller-supplied buffer to a given I/O port.
