.SH DESCRIPTION
The
.BR libj2_j2u_test_j2u ()
function checks whether any set bit in
.I b
is also set in
.IR a .
.PP
The
.BR libj2_j2u_test_ju ()
function checks whether any set bit in
.I b
is also set in the least significant half of
.IR a .
.PP
The
.BR libj2_j2u_test_high_ju ()
function checks whether any set bit in
.I b
is also set in the most significant half of
.IR a .
.PP
The
.BR libj2_j2u_test_bit ()
function checks whether the bit at position
.IR b ,
counting from 0 at the least significant bit,
is set in
.IR a .
.PP
The arguments are assumed to be
.RI non- NULL .

.SH RETURN VALUE

and
.BR libj2_j2u_test_bit ()
functions return 1 if the test passes, and 0 otherwise.

.SH ERRORS
The above listed functions cannot fail.
