MORIN 0 siblings, 1 reply; 7+ messages in thread From: Brendan Heading @ 2015-08-22 21:45 UTC (permalink / raw) To: buildroot Yann, I submitted a patch similar to this about a week ago. Not sure if you spotted it or not. When signal() is being used (as it will be when __UCLIBC__ is defined) the handler should take an int as a parameter, not a sigval_t. I was going to take this up with the developers as I can't see a good reason why the behaviour is different for uclibc and non-uclibc environments, and in any case CLOCK_REALTIME is almost certainly not what they want. But I haven't had a spare moment to write a test case to prove that the timer code used in the non-uclibc version would work just as well under uclibc. regards Brendan On 22 August 2015 at 22:38, Yann E.

But now, I see that it was marked rejected, hence the reason I did not see it. > When signal() is being used (as it will be when __UCLIBC__ is defined) > the handler should take an int as a parameter, not a sigval_t. > > I was going to take this up with the developers as I can't see a good > reason why the behaviour is different for uclibc and non-uclibc > environments, and in any case CLOCK_REALTIME is almost certainly not > what they want.
