Call this function before using any other GTK+ functions in your GUI
applications. It will initialize everything needed to operate the
toolkit and parses some standard command line options.
Although you are expected to pass the argc, argv parameters from main() to
this function, it is possible to pass NULL if argv is not available or
commandline handling is not required.
argc and argv are adjusted accordingly so your own code will
never see those standard arguments.
Since 2.18, GTK+ calls signal (SIGPIPE, SIG_IGN)
during initialization, to ignore SIGPIPE signals, since these are
almost never wanted in graphical applications. If you do need to
handle SIGPIPE for some reason, reset the handler after gtk_init(),
but notice that other libraries (e.g. libdbus or gvfs) might do
similar things.
