Description
Packit ae235b 
A GThreadedSocketService is a simple subclass of GSocketService
Packit ae235b 
that handles incoming connections by creating a worker thread and
Packit ae235b 
dispatching the connection to it by emitting the
Packit ae235b 
“run” signal in the new thread.
Packit ae235b 
The signal handler may perform blocking IO and need not return
Packit ae235b 
until the connection is closed.
Packit ae235b 
The service is implemented using a thread pool, so there is a
Packit ae235b 
limited amount of threads available to serve incoming requests.
Packit ae235b 
The service automatically stops the GSocketService from accepting
Packit ae235b 
new connections when all threads are busy.
Packit ae235b 
As with GSocketService, you may connect to “run”,
Packit ae235b 
or subclass and override the default handler.

Packit ae235b 
               gpointer                user_data)
Packit ae235b 
The ::run signal is emitted in a worker thread in response to an
Packit ae235b 
incoming connection. This thread is dedicated to handling
Packit ae235b 
connection
Packit ae235b 
 and may perform blocking IO. The signal handler need
Packit ae235b 
not return until the connection is closed.
