SSL_read_ex() and SSL_write_ex() function only exists in openssl v1.1.1 and higher version. refer to: https://github.com/openssl/openssl/commit/4ee7d3f94590d3766c28eed03b969f338ddf96dc and https://github.com/openssl/openssl/commit/7ee8627f6eb7cf63b34d2701d76bb66f6db811e5#diff-38e1eecb6013c2fe8bf194e5020ce1afd6e31c371d7849e041464ad822fe745bR1653
