This is a wrapper round the platform's socket routines.</p> <p>BIO_read_ex() and BIO_write_ex() read or write the underlying socket. BIO_puts() is supported but BIO_gets() is not.</p> <p>If the close flag is set then the socket is shut down and closed when the BIO is freed.</p> <p>BIO_new_socket() returns a socket BIO using <b>sock</b> and <b>close_flag</b>.</p> <h1 id="NOTES">NOTES</h1> <p>Socket BIOs also support any relevant functionality of file descriptor BIOs.</p> <p>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.</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>BIO_s_socket() returns the socket BIO method.</p> <p>BIO_new_socket() returns the newly allocated BIO or NULL is an error occurred.</p> <h1 id="COPYRIGHT">COPYRIGHT</h1> <p>Copyright 2000-2016 The OpenSSL Project Authors.
