Method

GioSocketClientconnect_async

since: 2.22

Declaration 

void
g_socket_client_connect_async (
  GSocketClient* client,
  GSocketConnectable* connectable,
  GCancellable* cancellable,
  GAsyncReadyCallback callback,
  gpointer user_data
)

Description

This is the asynchronous version of g_socket_client_connect().

You may wish to prefer the asynchronous version even in synchronous command line programs because, since 2.60, it implements RFC 8305 “Happy Eyeballs” recommendations to work around long connection timeouts in networks where IPv6 is broken by performing an IPv4 connection simultaneously without waiting for IPv6 to time out, which is not supported by the synchronous call. (This is not an API guarantee, and may change in the future.)

When the operation is finished callback will be called. You can then call g_socket_client_connect_finish() to get the result of the operation.
