Call this function before using any other GdkGLExt functions in your applications. It will initialize everything needed to operate the library and parses some standard command line options. @argc and standard arguments. <note><para>This function will terminate your program if it was unable to initialize the library for some reason. If you want your program to fall back to a textual interface you want to call gdk_gl_init_check() instead.</para></note> Address of the <parameter>argc</parameter> parameter of your main() function. Changed if any arguments were handled. Address of the <parameter>argv</parameter> parameter of main(). Any parameters understood by gdk_gl_init() are stripped before return. This function does the same work as gdk_gl_init() with only initialized. Instead it returns %FALSE on failure. This way the application can fall back to some other means of communication with the user - for example a curses or command line interface. %FALSE otherwise. %TRUE if the GUI has been successfully initialized, Address of the <parameter>argc</parameter> parameter of your <function>main()</function> function. Changed if any arguments were handled. Address of the <parameter>argv</parameter> parameter of <function>main()</function>. Any parameters understood by gdk_gl_init() are stripped before return. Indicates whether the window system supports the OpenGL extension (GLX, WGL, etc.). TRUE if OpenGL is supported, FALSE otherwise. Indicates whether the window system supports the OpenGL extension (GLX, WGL, etc.). TRUE if OpenGL is supported, FALSE otherwise. the #GdkDisplay where the query is sent to. Determines whether a given OpenGL extension is supported. There must be a valid current rendering context to call gdk_gl_query_gl_extension(). gdk_gl_query_gl_extension() returns information about OpenGL extensions only. This means that window system dependent extensions (for example, GLX extensions) are not reported by gdk_gl_query_gl_extension(). supported. TRUE if the OpenGL extension is supported, FALSE if not name of OpenGL extension. Returns the version numbers of the OpenGL extension to the window system. In the X Window System, it returns the GLX version. In the Microsoft Windows, it returns the Windows version. FALSE if it fails, TRUE otherwise. returns the major version number of the OpenGL extension. returns the minor version number of the OpenGL extension. Returns the version numbers of the OpenGL extension to the window system. In the X Window System, it returns the GLX version. In the Microsoft Windows, it returns the Windows version. FALSE if it fails, TRUE otherwise. the #GdkDisplay where the query is sent to. returns the major version number of the OpenGL extension. returns the minor version number of the OpenGL extension.
