[ELDK] using other clocks with timer_create

[Seimon Williams]

Hi,

We're using ELDK 4.0 on an arm9 based project and I'm having some trouble with the timer_create call.

I believe I need to use the CLOCK_MONOTONIC clock when I call timer_create so that the timer is not affected by a system time change as it is with CLOCK_REALTIME, but when I try to call timer_create I get EINVAL which indicates that the clock is not supported. I'm using kernel 2.6.15 and I thought that the Monotonic clock was supported.

So I looked deeper into the glibc-2.3.5 code from the ELDK Source CD, and noticed a million #ifdefs! I'm not too sure which bit is used and which isn't at the moment, but I think basically my question is if I rebuild glibc and somehow point it at my kernel code will I get the use of the monotonic clock? If so, can anyone give me some quick dummy pointers as to how to go about that - it scares me!

Thanks for your time,

Seimon
