How to use Unix Domain socket in CC2534?

Dear sir,

Recently we meet a problem about socket communication in CC2534.

We use standard socket in server and client now, but this kind of communication will bind a port that is open.

Our sercurity scan tool will account this port isn't safe.

We check CC2534 source code and find the Unix Domain socket that is a safe socket communication.

How we switch socket to Unix Domain socket?

Please help us to modify code.

Thanks!

#ifdef NPI_UNIX

         // Create the socket

         sNPIlisten = socket(AF_UNIX, SOCK_STREAM, 0);

         // Bind socket to a Unix domain address

         local.sun_family = AF_UNIX;

         strcpy(local.sun_path, "echo_socket");

         unlink(local.sun_path);

         len = strlen(local.sun_path) + sizeof(local.sun_family);

         if (bind(sNPIlisten, (struct sockaddr *)&local, len) == -1)

         {

                   perror("bind");

                   writeToNpiLnxLog("Port is probably already in use, please select an available port\n");

                   debug_printf("Port is probably already in use, please select an available port\n");

                   npi_ipc_errno = NPI_LNX_ERROR_IPC_SOCKET_BIND;

                   NPI_LNX_IPC_Exit(NPI_LNX_FAILURE, TRUE);

         }

#else

         sNPIlisten = socket(servinfo->ai_family, servinfo->ai_socktype,

                            servinfo->ai_protocol);

         int yes = 1
