VideoPortReadPortBufferUlong

VOID VideoPortReadPortBufferUlong(

PULONG  Port,
PULONG  Buffer,
ULONG  Count
);

VideoPortReadPortBufferUlong reads a number of ULONG values from a mapped I/O port into a buffer.

Parameters

Port

Points to the I/O port. The given Port must be in a mapped I/O-space range returned by VideoPortGetDeviceBase.

Buffer

Points to a buffer into which the ULONG values are read.

Count

Specifies the number of ULONG values to be transferred into the buffer.

Comments

The buffer must be large enough to contain at least the specified number of ULONG values.

A miniport’s HwVidInterrupt or HwVidSynchronizeExecutionCallback function can call VideoPortReadPortBufferUlong.
