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 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.
The type VOID_FUNC is defined as follows:
typedef void VOID_FUNC(void);

This is a function pointer to a user function to do deinstall an interrupt from the system. This
function must be from the type INTERRUPT_FUNC which is defined as follows: :
typedef AiUint8 INTERRUPT_SET_FUNC ( AiUint8 vector,
AiUint8 level, VOID_FUNC *intFuntion);
