Specifies the type of the setup function passed to g_spawn_async(), g_spawn_sync() and g_spawn_async_with_pipes(), which can, in very limited ways, be used to affect the child's execution..

The Main Event Loop - Guile-GLib - GNU This method goes over a list of pending source . #include <gtkmm.h> #include <libgnomedbmm.h>. The function waits until an event to process is . Namespace GLib - 2.0 GLib is a general-purpose, portable utility library, which provides many useful data types, macros, type conversions, string utilities, file utilities, a mainloop abstraction, and so on. Do not forget to call dbus_connection_setup_with_g_main function since the connection was created from dbus_bus_get function, otherwise the GLib mainloop and D-BUS callbacks will not work properly and will you be very sad, belive me. --. The global-default (accessed using g_main_context_default ()) is what's run by GTK+ when you call gtk_main ().

If I start my service in the test, the event loop blocks the test from completing. libuv enforces an asynchronous, event-driven style of programming. On Windows, the function is called in the parent. Minimal Bluetooth BLE central client on Linux using BlueZ Topics. This tutorial targets the GStreamer 1.0 API which all .

With GLib-based stuff generally there's a goal to hide threads and make it so apps only see the one thread. All libgnomedbmm programs must include the libgnomedbmm headers. The libusb documentation also includes more details about . Glib uses Priority Scheduling Dependencys are resolved with inherited priorities The Timer has a single parent, and multiple childs If the timer has "no" parent, the parent variable points to itself If the timer has "no" childs, the variable is null If a new timer is created out of another timer it gets the same priority as its father No Starvation
