glib main loop explained

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 A main loop just iterates a context. sd_event_run(3) - Linux manual page - Michael Kerrisk getting the HOWTO in correct format, finding all the typos, etc. GMainLoop - Philip Withnall inactivity log for davidz: Writing a C library, part 2 - Blogger Here's the commit. This is causing hangs in QEMU. Bug 761102 - Increase performance for main loop We will now explain each line of the example. This is part two in a series of blog-posts about best practices for writing C libraries. If I understand correctly the GLib, there is no need to launch the mainloop for a such treatment. A Good Understanding of D-BUS - An IPC Mechanism in Linux While this may be a bug in QEMU, depending on how glib handles backwards bug-compatibility you may want to revert this patch. GSpawnChildSetupFunc void (*GSpawnChildSetupFunc) (gpointer user_data);Specifies the type of the setup function passed to g_spawn_async(), g_spawn_sync() and g_spawn_async_with_pipes().On POSIX platforms it is called in the child after GLib has performed all the setup it plans to perform but before calling exec().On POSIX actions taken in this function will thus only affect the child, not the . Patch 2 and patch 3 completely separate the way the main loop waits on POSIX and w32 systems, and drop glib source handling from the w32 main loop. GLib provides the fundamental data types and system integration points to avoid duplicated code in applications. One of the important features of GMainContext is its support for 'default' contexts. . The examples below show how to export Qt objects to Python and emit a D-Bus signal when a Qt signal is emitted. This handler will be called whenever the pipeline emits a . When a property in a DBus object changes, the same change is reflected in the proxy. The event loop waits for events such as mouse press, mouse move, or keyboard press events. Getting Started ¶. glib/ChangeLog.pre-2-0 at master · winlibs/glib · GitHub As memory is … Continue reading "Creating a Circular Buffer in C and C++" To use a bus, attach a message handler to the bus of a pipeline using gst_bus_add_watch (). Simple Example - gtkmm def initialize( self): "" "Initialize bluez DBus communication. This has allowed people to plug Qt into the Glib main loop fairly easily, resulting in an application that can use any of the Qt, GTK+, KDE, and GNOME APIs. However, if there are many touch and dbus events in the GUI Thread, it will hang.
