As stated in GTK documentation about gtk_init():
* "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."
* "It is possible to pass NULL if argv is not available or commandline
handling is not required."
