=head1 DESCRIPTION
The B<BIO_METHOD> type is a structure used for the implementation of new BIO
-types. It provides a set of of functions used by OpenSSL for the implementation
+types. It provides a set of functions used by OpenSSL for the implementation
of the various BIO capabilities. See the L<bio> page for more information.
BIO_meth_new() creates a new B<BIO_METHOD> structure. It should be given a
in response to the application calling BIO_callback_ctrl(). The parameters for
the function have the same meaning as for BIO_callback_ctrl().
+=head1 RETURN VALUES
+
+BIO_get_new_index() returns the new BIO type value or -1 if an error occurred.
+
+BIO_meth_new(int type, const char *name) returns a valid B<BIO_METHOD> or NULL
+if an error occurred.
+
+The B<BIO_meth_set> functions return 1 on success or 0 on error.
+
+The B<BIO_meth_get> functions return the corresponding function pointers.
