DESCRIPTION¶

The ck_pr_inc(3) family of functions atomically increment the value pointed to by target.

RETURN VALUES¶

The ck_pr_inc_zero family of functions set the value pointed to by z to true if the result of the increment operation was 0. The functions set the value pointed to by z false otherwise. The ck_pr_inc_is_zero family of function return true if the result of the decrement operation was 0 and false otherwise.
