DESCRIPTION¶
Theck_pr_btc
(3) family of
functions atomically fetch the value of the bit in
target at index bit_index and set
that bit to its complement.
RETURN VALUES¶
These family of functions return the original value of the bit at offset bit_index that is in the value pointed to by target.SEE ALSO¶
