VteReaper

VteReaper — A singleton object which catches SIGCHLD signals and converts them into GObject-style "child-exited" signals

Synopsis

                    VteReaper;
int                 vte_reaper_add_child                (GPid pid);
VteReaper *         vte_reaper_get                      (void);

Signals

  "child-exited"                                   : Run Last

Description

Because an application may need to be notified when child processes exit, and because there is only one SIGCHLD handler, the VteTerminal widget relies on a VteReaper to watch for SIGCHLD notifications and retrieve the exit status of child processes which have exited. When glib provides child_watch functionality, the VteReaper merely acts as a proxy for glib's own functionality.

Since 0.11.11

Details

VteReaper

typedef struct _VteReaper VteReaper;

Warning

VteReaper is deprecated and should not be used in newly-written code.

The reaper object.

vte_reaper_add_child ()

int                 vte_reaper_add_child                (GPid pid);

Warning

vte_reaper_add_child is deprecated and should not be used in newly-written code.

Ensures that child-exited signals will be emitted when pid exits. This is necessary for correct operation when running with glib versions >= 2.4.

pid :

 the ID of a child process which will be monitored

Returns :

 the new source ID Since 0.11.11

vte_reaper_get ()

VteReaper *         vte_reaper_get                      (void);

Warning

vte_reaper_get is deprecated and should not be used in newly-written code.

Finds the address of the global VteReaper object, creating the object if necessary.

Returns :

 the global VteReaper object, which should not be unreffed.

Signal Details

The "child-exited" signal

void                user_function                      (VteReaper *vtereaper,
                                                        gint       arg1,
                                                        gint       arg2,
                                                        gpointer   user_data)      : Run Last

Emitted when the VteReaper object detects that a child of the current process has exited.

vtereaper :

 the object which received the signal

arg1 :

 the process ID of the exited child

arg2 :

 the status of the exited child, as returned by waitpid()

user_data :

 user data set when the signal handler was connected.
