67/* The usage is quite simple, initialize an ASN1 structure,
68 * get a BIO from it then any data written through the BIO
69 * will end up translated to approptiate format on the fly.
70 * The data is streamed out and does *not* need to be

72 *
73 * When the BIO is flushed the output is finalized and any

75 *
76 * The BIO is a 'proper' BIO and can handle non blocking I/O
