This function applies interrupt specific parameters to the board, specified in
px_PCI_Info. This command can be called after AiVmeExamineSlot() for a board on
the VME bus or after AiPciGetHeader() for a board on a local PCI bus.

Pointer to the PCI info element for this board. It determines for which board the
additional settings are. To get this parameter please use the output of
AiVmeExamineSlot() or AiPciGetHeader()

Using this parameter the interrupt level can be applied to the board.
Note: if two PMC boards are driven on the same AVC-2 carrier, both must
have the same interrupt level and vector.

Using this parameter the interrupt vector can be applied to the board.

have the same interrupt level and vector.

According to specifics of your VME system it can be very different to set and enable the
interrupt to the specific level and vector. So this parameter is a function pointer to a routine,
which can set the interrupt vector to the interrupt vector table in the host VME system for
selected interrupt level number. This function must be from the type
INTERRUPT_SET_FUNC which is defined in ‘API429.h’ as follows:
typedef AiUint8 INTERRUPT_SET_FUNC ( AiUint8 vector,
AiUint8 level, VOID_FUNC *intFuntion);
This is a callback function which will be called from the ‘AviInitVmeInt’ to make the interrupt
settings. The parameter ‘*intFuntion’ of type VOID_FUNC is the function pointer which
should be called in case of interrupt. This function is a driver internal interrupt function
which handles the hardwae interrupt on the AIM board and distributes to the user interrupt
functions.
