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.
