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

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

Functions

vte_reaper_add_child ()

int
vte_reaper_add_child (GPid pid);

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.

Parameters

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);

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.

Types and Values

VteReaper

typedef struct _VteReaper VteReaper;

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

The reaper object.
