3.1.2 PIO_GetConfigAddressSpace
PIO_GetConfigAddressSpace(wBoardNo,*wBase,*wIrq, *wSubVendor,
*wSubDevice, *wSubAux,*wSlotBus,*wSlotDevice)
• wBoardNo=0 to N Æ totally N+1 boards found by PIO_DriveInit(...)
• wBase Æ base address of the board control word
• wIrq Æ allocated IRQ channel number of this board
• wSubVendor Æ subVendor ID of this board
• wSubDevice Æ subDevice ID of this board
• wSubAux Æ subAux ID of this board
• wSlotBus Æ hardware slot ID1 of this board
• wSlotDevice Æ hardware slot ID2 of this board
The user can use this function to save resource of all OME-PIO/PISO cards
installed in this system. Then the application program can control all functions of
OME-PIO/PISO series card directly.
