-BIO_new, BIO_set, BIO_up_ref, BIO_free, BIO_vfree, BIO_free_all - BIO allocation and freeing functions
+BIO_new, BIO_up_ref, BIO_free, BIO_vfree, BIO_free_all,
+BIO_set - BIO allocation and freeing functions
=head1 SYNOPSIS
The BIO_new() function returns a new BIO using method B<type>.
-BIO_set() sets the method of an already existing BIO.
-
BIO_up_ref() increments the reference count associated with the BIO object.
BIO_free() frees up a single BIO, BIO_vfree() also frees up a single BIO
Calling BIO_free_all() on a single BIO has the same effect as calling BIO_free()
on it other than the discarded return value.
+=head1 HISTORY
+
+BIO_set() was removed in OpenSSL 1.1.0 as BIO type is now opaque.
