Overview

The ck_pr_dec(3) family of functions atomically decrement the value pointed to by target.

Return values

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