DESCRIPTION
       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.
