DESCRIPTION
The
Fn ck_pr_btc 3
family of functions atomically fetch the value
of the bit in
Fa target
at index
Fa bit_index
and set that bit to its complement.
RETURN VALUES
These family of functions return the original value of
the bit at offset
Fa bit_index
that is in the value pointed to by
Fa target .
