VideoPortReadRegisterBufferUlong

VOID VideoPortReadRegisterBufferUlong(

PULONG  Register,
PULONG  Buffer,
ULONG  Count
);

VideoPortReadRegisterBufferUlong reads a number of ULONG values from a mapped device memory range into a buffer.

Parameters

Register

Points to the register. The given Register must be in a mapped memory-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 VideoPortReadRegisterBufferUlong.
