how to pass a pointer or array name to the interrupt function?

hi, i tried and it works!

this is the code:

void ft245_interrupt(alt_u32 precision_data[500])

{

.....

}

int main()

{

alt_u32 i=0;

alt_u32 precision_data_1[500]={0};

i=alt_irq_enabled();

alt_ic_isr_register (NIOS_FT245_INTERFACE_0_IRQ_INTERRUPT_CONTROLLER_ID,

NIOS_FT245_INTERFACE_0_IRQ,

ft245_interrupt,

precision_data_1,

NULL);

but the eclipse give me a warning
