BIO_s_socket() returns the socket BIO method. This is a wrapper round the platform's socket routines.

       BIO_read_ex() and BIO_write_ex() read or write the underlying socket.  BIO_puts() is supported but
       BIO_gets() is not.

       If the close flag is set then the socket is shut down and closed when the BIO is freed.

       BIO_new_socket() returns a socket BIO using sock and close_flag.

       BIO_s_socket, BIO_new_socket - socket BIO

       Socket BIOs also support any relevant functionality of file descriptor BIOs.

       The reason for having separate file descriptor and socket BIOs is that on some platforms sockets are not
       file descriptors and use distinct I/O routines, Windows is one such platform. Any code mixing the two
       will not work on all platforms.

BIO_s_socket() returns the socket BIO method.

       BIO_new_socket() returns the newly allocated BIO or NULL is an error occurred.
