=head1 DESCRIPTION
When a prime has been found, B<BN_GENCB_call(cb, 2, i)> is called.
+=item *
+
+The callers of BN_generate_prime_ex() may call B<BN_GENCB_call(cb, i, j)> with
+other values as described in their respective man pages; see L</SEE ALSO>.

=back
The prime may have to fulfill additional requirements for use in
B<nchecks == BN_prime_checks>, a number of iterations is used that
yields a false positive rate of at most 2^-64 for random input.
The error rate depends on the size of the prime and goes down for bigger primes.
-The rate is 2^-80 starting at 308 bits, 2^-112 at 852 bit, 2^-128 at 1080 bits,
-2^-192 at 3747 bit and 2^-256 at 6394 bit.

When the source of the prime is not random or not trusted, the number
of checks needs to be much higher to reach the same level of assurance:
the type of the callback and will invoke B<callback(a, b, gencb)> for new
style callbacks or B<callback(a, b, cb_arg)> for old style.
