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.
