I’ll explain again my question:

The atomic time devision (known also as clock tic) in windows is
CLK_TCK = 1000.

I was woundering what is the parallle one in QNX ?

Oppse, I thought I was reading the qdn.public.qnx2
conference. For QNX4 or QNX6, take a look at the
clock() function.

Parallel would probably be called tick size ro clock resolution – but
it isn’t a hard-coded value.

Under QNX6, clock_getres() will allow you to query it, and clock_setres()
will allow you to set it. It defaults to 10ms on slow machines and 1 ms
on fast machines.

(Under QNX4, it defaults to 10ms.)
