module Gio::SocketConnectable


Objects that describe one or more potential socket endpoints implement #GSocketConnectable. Callers can then use g_socket_connectable_enumerate() to get a #GSocketAddressEnumerator to try out each socket address in turn until one succeeds, as shown in the sample code below.

|[ MyConnectionType * connect_to_host (const char *hostname, guint16 port, GCancellable *cancellable, GError **error) { MyConnection *conn = NULL; GSocketConnectable *addr; GSocketAddressEnumerator *enumerator; GSocketAddress *sockaddr; GError *conn_error = NULL;

addr = g_network_address_new (hostname, port); enumerator = g_socket_connectable_enumerate (addr); g_object_unref (addr);

// Try each sockaddr until we succeed. Record the first connection error, // but not any further ones (since they'll probably be basically the same // as the first). while (!conn && (sockaddr = g_socket_address_enumerator_next (enumerator, cancellable, error)) { conn = connect_to_sockaddr (sockaddr, conn_error ? NULL : &conn_error); g_object_unref (sockaddr); } g_object_unref (enumerator);

if (conn) { if (conn_error) { // We couldn't connect to the first address, but we succeeded // in connecting to a later address. g_error_free (conn_error); } return conn; } else if (error) { /// Either initial lookup failed, or else the caller cancelled us. if (conn_error) g_error_free (conn_error); return NULL; } else { g_error_propagate (error, conn_error); return NULL; } } ]|
