Hi again!

Ok I tried to implement the alt_irq_interruptible() and alt_irq_non_interruptible() functions but I get an undefined reference error: 

undefined reference to `alt_irq_interruptible'
undefined reference to `alt_irq_non_interruptible'

The <sys/alt_irq.h> headerfile is included. Is there any other headerfile required?

I also checked the "HAL API reference" (can be found here: http://www.altera.com/literature/hb/nios2/n2sw_nii52010.pdf) and noticed that both functions are not listed (any longer?). Maybe those are deprecated? What would be the alternative?

Thanks in advance!
