+ BIO *BIO_pop(BIO *b);
+ void BIO_set_next(BIO *b, BIO *next);
=head1 DESCRIPTION
becomes a single BIO with no association with the original chain,
it can thus be freed or attached to a different chain.
+BIO_set_next() replaces the existing next BIO in a chain with the BIO pointed to
+by B<next>. The new chain may include some of the same BIOs from the old chain
+or it may be completely different.
