Before the video miniport driver can call the AGP functions, it must obtain function pointers by passing VideoPortServicesAgp to the VideoPortQueryServices function. The video miniport driver also passes a VIDEO_PORT_AGP_INTERFACE or VIDEO_PORT_AGP_INTERFACE_2 structure to VideoPortQueryServices. On return, that structure contains pointers to the AGP functions implemented by the video port driver.
