Hi,
I’ve been using QNX timers (POSIX style), unfortunately
I haven’t been able to get a resolution higher that 0.5ms.
Is is possible to get more resolution with standard timers ?
Do exist other timers with better performance ?
Best Regards,

With QNX4 you can get down to like 100us I beleive, but
you’d better have a fast CPU.
… which you do using the “ticksize” utility. I believe what you
want is “ticksize -e 100000”, which will attempt to set the ticksize
at 100000 nsec, despite that ticksize only claims to allow down to
500000 nsec.
