IORD_ALTERA_VIC_INT_PENDING() & alt_irq_pending ()

Hi,

I'm trying to use FreeRTOS with the VIC on NIOS II.

This is possible if you rewrite the alt_irq_handle routine for the VIC driver (not provided by Intel/Altera).

What's the difference between alt_irq_pending and IORD_ALTERA_VIC_INT_PENDING functions?

Are they similar?

Best Regards
