+.SH DESCRIPTION
+The above listed functions calculate
+the bitwise inverse (NOT) of
+.I a
+if the sign-bit is set in
+.IR a ,
+that is, if and only if
+.I a
+is negative: for each bit, the XOR with
+the sign-bit is calculated. The result,
+which is always non-negative, is stored in
+.IR r ,
+except in the case of the
+.BR libj2_j2i_xor_sign ()
+function, where the result is stored in
+.IR a .
+.PP
+The arguments are assumed to be
+.RI non- NULL .
+
+.SH RETURN VALUE
+None.
+
+.SH ERRORS
+The above listed functions cannot fail.
+
+.SH HISTORY
+The
+.BR libj2_j2i_xor_sign (),
+.BR libj2_j2i_xor_sign_to_j2i (),
+and
+.BR libj2_j2i_xor_sign_to_j2u ()

+The above listed functions calculate
