Purpose Run just b efore the interrupt service routine

Syntax int __cdecl your_company_name_boardPreHook(xpcPCIDevice

*pciInfo);

Argument

pciInfo

Pointer to the PciDevice structure.

Description your_company_name_boardPreHook runs just before the model-level

interrupt service routine (either a function-call subsystem or entire

model) is called.

Return This function must check the status register on the board to determine

if the board caused the interrupt. It returns one of the following:

•

XPC_RUN_ISR — If the function determines that the board did cause

the interrupt, the function must perform the required operation to

stop the board from generating the interrupt. The function then

returns this value.

•

XPC_DROP_ISR — If the function determines that the board did not

cause the interrupt, this function returns this value.
