General discussion • Pi 4 Model B QNX GPIO interrupt set up

HI currently, I am porting QNX OS in Raspberry Pi 4 Model B, and try to implement GPIO interrupt for Touch function,
I try to config GPIO23 or GPIO21 to be an interrupt pin usage, When I use QNX function InterruptAttachEvent to config interrupt pin,
It seems not work for me.
Does anybody know how to find out Interrupt vector numbers to map Raspberry Pi 4 Model B GPIO interrupt pins ?
I try to use 23 or 21 to be a Interrupt vector number as an input, but it seems not work for me,
