Features

  • No additional dependecies
  • Single header library interface librws.h with public methods
  • Thread safe
  • Send/receive logic in background thread

Installation with CocoaPods

Podfile

pod 'librws'

Example

Create and store websocket object handle
  // Define variable or field for socket handle
  rws_socket _socket = NULL;
  ............
  // Create socket object
  _socket = rws_socket_create();
Set websocket connection url
// Combined url: "ws://echo.websocket.org:80/"
rws_socket_set_scheme(_socket, "ws");
rws_socket_set_host(_socket, "echo.websocket.org");
rws_socket_set_port(_socket, 80);
rws_socket_set_path(_socket, "/");
Set websocket responce callbacks

Warning: rws_socket_set_on_disconnected is required

// Main callbacks functions
// callback trigered on socket disconnected with/without error
static void on_socket_disconnected(rws_socket socket) {
  // process error
  rws_error error = rws_socket_get_error(socket);
  if (error) { 
    printf("nSocket disconnect with code, error: %i, %s", rws_error_get_code(error), rws_error_get_description(error)); 
  }
  // forget about this socket object, due to next disconnection sequence
  _socket = NULL;
}
// callback trigered on socket connected and handshake done
static void on_socket_connected(rws_socket socket) {
  printf("nSocket connected");
}
// callback trigered on socket received text
static void on_socket_received_text(rws_socket socket, const char * text, const unsigned int length) {
  printf("nSocket text: %s", text);
}
..................
// Set socket callbacks
rws_socket_set_on_disconnected(_socket, &on_socket_disconnected); // required
rws_socket_set_on_connected(_socket, &on_socket_connected);
rws_socket_set_on_received_text(_socket, &on_socket_received_text);
Connect
rws_socket_connect(_socket);
Send message to websocket
const char * example_text =
  "{"version":"1.0","supportedConnectionTypes":["websocket"],"minimumVersion":"1.0","channel":"/meta/handshake"}";
rws_socket_send_text(_socket, example_text);
Disconnect or delete websocket object

Since socket can be connected and we need to send disconnect mesage, not just lazy close, need to wait and than delete object.
Thats why just call rws_socket_disconnect_and_release, its thread safe, and forget about this socket object.

rws_socket_disconnect_and_release(_socket);
_socket = NULL;
