2023 * SSL_select_next_proto implements the standard protocol selection. It is

2026 * vector of 8-bit, length prefixed byte strings. The length byte itself is
2027 * not included in the length. A byte string of length 0 is invalid. No byte
2028 * string may be truncated. The current, but experimental algorithm for
2029 * selecting the protocol is: 1) If the server doesn't support NPN then this
2030 * is indicated to the callback. In this case, the client application has to
2031 * abort the connection or have a default application level protocol. 2) If
2032 * the server supports NPN, but advertises an empty list then the client
2033 * selects the first protcol in its list, but indicates via the API that this
2034 * fallback case was enacted. 3) Otherwise, the client finds the first
2035 * protocol in the server's list that it supports and selects this protocol.
2036 * This is because it's assumed that the server has better information about
2037 * which protocol a client should use. 4) If the client doesn't support any
2038 * of the server's advertised protocols, then this is treated the same as
2039 * case 2. It returns either OPENSSL_NPN_NEGOTIATED if a common protocol was
2040 * found, or OPENSSL_NPN_NO_OVERLAP if the fallback case was reached.
