=head1 DESCRIPTION
These functions implement Montgomery multiplication. They are used
-automatically when BN_mod_exp(3) is called with suitable input,
+automatically when L<BN_mod_exp(3)|BN_mod_exp(3)> is called with suitable input,
but they may be useful when several operations are to be performed
using the same modulus.
BN_MONT_CTX_init() and BN_MONT_CTX_free() have no return values.
For the other functions, 1 is returned for success, 0 on error.
-The error codes can be obtained by ERR_get_error(3).
+The error codes can be obtained by L<ERR_get_error(3)|ERR_get_error(3)>.
