DESCRIPTION

32     The ck_pr_bts(3) family of functions atomically fetch the value of the
33     bit in target at index bit_index and set that bit to 1.
34

RETURN VALUES

36     This family of functions returns the original value of the bit at offset
37     bit_index that is in the value pointed to by target.
