dxmini.h contains the following programming interfaces:
Callback functions
| PDX_BOBNEXTFIELD The DxBobNextField callback function bobs the next field of interleaved data. |
| PDX_ENABLEIRQ The DxEnableIRQ callback function indicates to the video miniport driver which IRQs should be enabled or disabled. |
| PDX_FLIPOVERLAY The DxFlipOverlay callback function is called when a client of the video miniport driver wants to flip the overlay or when autoflipping is enabled. |
| PDX_FLIPVIDEOPORT The DxFlipVideoPort callback function is called when a client of the video miniport driver wants to flip the video port extensions (VPE) object or when autoflipping is enabled. |
| PDX_GETCURRENTAUTOFLIP The DxGetCurrentAutoflip callback function is called when the device is hardware autoflipping and a client of the video miniport driver wants to know which surface is receiving the current field of video data for capture purposes. |
| PDX_GETIRQINFO The DxGetIRQInfo callback function indicates that the driver manages the interrupt request. |
| PDX_GETPOLARITY The DxGetPolarity callback function returns the polarity (even or odd) of the current field being written by the video port extensions (VPE) object. |
| PDX_GETPREVIOUSAUTOFLIP The DxGetPreviousAutoflip callback function is called when the device is hardware autoflipping and a client of the video miniport driver wants to know which surface received the previous field of video data for capture purposes. |
| PDX_GETTRANSFERSTATUS The DxGetTransferStatus callback function is used by DirectDraw to determine which hardware bus master has completed. |
| PDX_IRQCALLBACK The IRQCallback function performs operations related to the IRQ that occurred. |
| PDX_LOCK The DxLock callback function is called when a client of the video miniport driver wants access to the frame buffer. |
| PDX_SETSTATE The DxSetState callback function is called when a client of the video miniport driver decides it wants to switch from bob mode to weave mode, and vice versa. |
| PDX_SKIPNEXTFIELD The DxSkipNextField callback function is called when the next field needs to be skipped or reenabled. |
| PDX_TRANSFER The DxTransfer callback function informs the driver to bus master data from a surface to the buffer specified in the memory descriptor list (MDL). |
