Description
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. argc and
argv are adjusted accordingly so your own code will
never see those standard arguments. Details
Note that there are some alternative ways to initialize GTK+:
if you are calling gtkParseArgs(), gtkInitCheck(),
gtkInitWithArgs() or gOptionContextParse() with
the option group returned by gtkGetOptionGroup(), you
don't have to call gtkInit.
PLEASE NOTE: This function will terminate your program if it was unable to initialize
the GUI for some reason. If you want your program to fall back to a
textual interface you want to call gtkInitCheck() instead. PLEASE NOTE: 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 gtkInit,
but notice that other libraries (e.g. libdbus or gvfs) might do
similar things.
