TLS_DETACH(3) libdill Library Functions TLS_DETACH(3) NAME tls_detach - terminates TLS protocol and returns the underlying socket SYNOPSIS #include <libdill.h> int tls_detach( int s, int64_t deadline); DESCRIPTION WARNING: This is experimental functionality and the API may change in the future. TLS is a cryptographic protocol to provide secure communication over the network. It is a bytestream protocol. This function does the terminal handshake and returns underlying socket to the user. The socket is closed even in the case of error. s: Handle of the TLS socket. deadline: A point in time when the operation should time out, in millisec- onds. Use the now function to get your current point in time. 0 means im- mediate timeout, i.e., perform the operation if possible or return without blocking if not. -1 means no deadline, i.e., the call will block forever if the operation cannot be performed. This function is not available if libdill is compiled with --disable-sock- ets option. This function is not available if libdill is compiled without --enable-tls option. RETURN VALUE In case of success the function returns underlying socket handle. In case of error it returns -1 and sets errno to one of the values below. ERRORS * EBADF: Invalid handle. * ECANCELED: Current coroutine was canceled. * ECONNRESET: Broken connection. * ENOTSUP: The handle is not a TLS protocol handle. * ETIMEDOUT: Deadline was reached. EXAMPLE int s = tcp_connect(&addr, -1); s = tls_attach_client(s, -1); bsend(s, "ABC", 3, -1); char buf[3]; ssize_t sz = brecv(s, buf, sizeof(buf), -1); s = tls_detach(s, -1); tcp_close(s); SEE ALSO brecv(3) brecvl(3) bsend(3) bsendl(3) now(3) tls_attach_client(3) tls_at- tach_client_mem(3) tls_attach_server(3) tls_attach_server_mem(3) tls_done(3) libdill TLS_DETACH(3)
