Function

GLibidle_add

since: 2.0

Declaration

guint
g_idle_add (
  GSourceFunc function,
  gpointer data
)

Description

Adds a function to be called whenever there are no higher priority events pending to the default main loop. The function is given the default idle priority, G_PRIORITY_DEFAULT_IDLE. If the function returns FALSE it is automatically removed from the list of event sources and will not be called again.

See [memory management of sources][mainloop-memory-management] for details on how to handle the return value and memory management of data.

This internally creates a main loop source using g_idle_source_new() and attaches it to the global GMainContext using g_source_attach(), so the callback will be invoked in whichever thread is running that main context. You can do these steps manually if you need greater control or to use a custom main context.
