GPIO interrupt reading timeout

[Gabriel Dinse via Xenomai]

Hello,

I currently have a loop rt_task for reading interrupts on a GPIO pin of 
my raspberry pi.

I'm using:
ret = read(pin, &value, sizeof(value));

but I don't want it to block forever, because my task should exit when 
there are not more interrupts to read. Can I use "select" for 
introducing a reading timeout on my loop and yet being "real-time"?

Thank you,
Gabriel Dinse
