DESCRIPTION
       The BIO_find_type() searches for a BIO of a given type in a chain,
       starting at BIO b. If type is a specific type (such as BIO_TYPE_MEM)
       then a search is made for a BIO of that type. If type is a general type
       (such as BIO_TYPE_SOURCE_SINK) then the next matching BIO of the given
       general type is searched for. BIO_find_type() returns the next matching
       BIO or NULL if none is found.

       Note: not all the BIO_TYPE_* types above have corresponding BIO
       implementations.

       BIO_next() returns the next BIO in a chain. It can be used to traverse
       all BIOs in a chain or used in conjunction with BIO_find_type() to find
       all BIOs of a certain type.

       BIO_method_type() returns the type of a BIO.

RETURN VALUES
       BIO_find_type() returns a matching BIO or NULL for no match.

       BIO_next() returns the next BIO in a chain.

       BIO_method_type() returns the type of the BIO b.

NOTES
       BIO_next() was added to OpenSSL 0.9.6 to provide a 'clean' way to
       traverse a BIO chain or find multiple matches using BIO_find_type().
       Previous versions had to use:

	next = bio->next_bio;

BUGS
       BIO_find_type() in OpenSSL 0.9.5a and earlier could not be safely
       passed a NULL pointer for the b argument.

EXAMPLE
       Traverse a chain looking for digest BIOs:

	BIO *btmp;
	btmp = in_bio; /* in_bio is chain to search through */

	do {
	       btmp = BIO_find_type(btmp, BIO_TYPE_MD);
	       if(btmp == NULL) break; /* Not found */
	       /* btmp is a digest BIO, do something with it ...*/
	       ...

	       btmp = BIO_next(btmp);
	} while(btmp);
