Whenever I get anything like this, I simply grep the header files. i.e.:

grep -R _SC_CLK_TCK /usr/include/* /usr/include/unistd.h:#define _SC_CLK_TCK 3

so, 3 is the answer!

Hi all!

I'm very new to using JNA (and in general to interfacing Java with C -- I guess there are quite a few years since I've done this the last time).

Right now I am trying to map the sys/times.h clock_t times(struct tms *) call. According to the documentation the returned values are measured in number of clock ticks per second, and to figure out what this value is I should be calling the function long sysconf(int) where the parameter should be _SC_CLK_TCK.

My problem is that I don't have any idea about the value of _SC_CLK_TCK, so I am pretty lost on how it would be possible for me to get the sysconf invocation working.

Any ideas? Many thanks in advance,
