## ◆ connect()

sigc::connection Glib::SignalChildWatch::connect | ( | const sigc::slot< void, GPid, int > & | slot,
|  | GPid | pid,
|  | int | priority = `PRIORITY_DEFAULT`
| ) |  |

Connects a child watch handler.

void child_watch_handler(GPid pid, int child_status) { ... }
Glib::signal_child_watch().connect(sigc::ptr_fun(&child_watch_handler), pid);

This method is not thread-safe. You should call it, or manipulate the returned sigc::connection object, only from the thread where the SignalChildWatch object's MainContext runs.

Parameters

  slot | A slot to call when child process pid exited.
  pid | The child process to watch for.
  priority | The priority of the new event source.

Returns
  A connection handle, which can be used to disconnect the handler.
