Index-Addressing

The board information integer MultiCam parameter implementing the index-addressing mechanism is DriverIndex.

When the MultiCam driver is launched, the hardware system is scanned and all present MultiCam compliant boards are reported.

The driver establishes a list of the boards, starting at index zero and incrementing by one up to the last available board. The order in which the boards are effectively scanned cannot be predicted, as it is BIOS dependent. However, for a given host computer and a identical insertion of the boards in the PCI slots, the numbering order will be consistently repeated.

Setting DriverIndex to a value between 0 and BoardCount–1 uniquely designates one of the boards. Any set or get function involving a "board information" parameter will address the designated board.

Getting DriverIndex returns the index of the presently selected MultiCam board.
