DESCRIPTION

The Fn ck_pr_dec 3 family of functions atomically decrement the value pointed to by Fa target .

RETURN VALUES

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