.SH DESCRIPTION
The above listed functions
calculate the bitwise NOR of
.I a
and
.IR b ;
for the functions where one of the
parameter uses a narrower, that
argument is extended with cleared
bits above it's most significant
bit; except that for the functions
.BR libj2_j2u_nor_bit ()
and
.BR libj2_j2u_nor_bit_to_j2u ()
the argument
.I b
is replaced with an argument with
all bits cleared, except the
.IR b th
bit (counting from 0 at the least
significant bit) which is set.
The result is written to
.IR r ,
or if the function doesn't not the
.I r
parameter, to
.IR a .
.PP
The arguments are assumed to be
.RI non- NULL .

.SH RETURN VALUE
None.

.SH ERRORS
The above listed functions cannot fail.
