PUCHAR
VC_GetFrameBuffer(
PDEVICE_INFO pDevInfo
);
The VC_GetFrameBuffer function returns a pointer to the system address space corresponding to the device’s frame buffer.
Parameters
pDevInfo
Pointer to the DEVICE_INFO structure returned by VC_Init.
Return Value
Pointer to the system address space to which the frame buffer is mapped.
Comments
A kernel-mode driver must call the VC_GetFrameBuffer function to obtain the mapped address of the device’s frame buffer. The frame buffer’s bus-relative physical address range is mapped to nonpaged system space by the VC_GetResources function.
