Description
A GThreadedSocketService is a simple subclass of GSocketService that handles incoming connections by creating a worker thread and dispatching the connection to it by emitting the “run” signal in the new thread.
The signal handler may perform blocking IO and need not return until the connection is closed.
The service is implemented using a thread pool, so there is a limited amount of threads available to serve incoming requests. The service automatically stops the GSocketService from accepting new connections when all threads are busy.
As with GSocketService, you may connect to “run”, or subclass and override the default handler.
Functions
g_threaded_socket_service_new ()
GSocketService *
g_threaded_socket_service_new (int max_threads);
Creates a new GThreadedSocketService with no listeners. Listeners must be added with one of the GSocketListener "add" methods.
Parameters
max_threads |
the maximal number of threads to execute concurrently handling incoming clients, -1 means no limit |
Since: 2.22
Types and Values
GThreadedSocketService
typedef struct _GThreadedSocketService GThreadedSocketService;
A helper class for handling accepting incoming connections in the glib mainloop and handling them in a thread.
Since: 2.22
Property Details
The “max-threads” property
“max-threads” gint
The max number of threads handling clients for this service.
Flags: Read / Write / Construct Only
Allowed values: >= -1
Default value: 10
Signal Details
The “run” signal
gboolean user_function (GThreadedSocketService *service, GSocketConnection *connection, GObject *source_object, gpointer user_data)
The ::run signal is emitted in a worker thread in response to an
incoming connection. This thread is dedicated to handling
connection
and may perform blocking IO. The signal handler need
not return until the connection is closed.
Parameters

connection |

source_object |
the source_object passed to |
|
user_data |
user data set when the signal handler was connected. |
