HZ question

I need to know the kernels value of HZ in a userland app.

getconf CLK_TCK
and
hz = sysconf (_SC_CLK_TCK)

both seem to return CLOCKS_PER_SEC which is defined as USER_HZ which is
defined as 100.

include/asm/param.h:

#ifdef __KERNEL__
# define HZ 1000 /* Internal kernel timer frequency */
# define USER_HZ 100 /* .. some user interfaces are in "ticks" */
# define CLOCKS_PER_SEC (USER_HZ) /* like times() */
#endif

Thanks in advance for any help
