GLXQUERYEXTENSION(3G)						   OpenGL Manual					     GLXQUERYEXTENSION(3G)

NAME
glXQueryExtension - indicate whether the GLX extension is supported C SPECIFICATION
Bool glXQueryExtension(Display * dpy, int * errorBase, int * eventBase); PARAMETERS
dpy Specifies the connection to the X server. errorBase Returns the base error code of the GLX server extension. eventBase Returns the base event code of the GLX server extension. DESCRIPTION
glXQueryExtension returns True if the X server of connection dpy supports the GLX extension, False otherwise. If True is returned, then errorBase and eventBase return the error base and event base of the GLX extension. These values should be added to the constant error and event values to determine the actual event or error values. Otherwise, errorBase and eventBase are unchanged. errorBase and eventBase do not return values if they are specified as NULL. SEE ALSO

GLXQUERYVERSION(3G)						   OpenGL Manual					       GLXQUERYVERSION(3G)

NAME
glXQueryVersion - return the version numbers of the GLX extension C SPECIFICATION
Bool glXQueryVersion(Display * dpy, int * major, int * minor); PARAMETERS
dpy Specifies the connection to the X server. major Returns the major version number of the GLX server extension. minor Returns the minor version number of the GLX server extension. DESCRIPTION
glXQueryVersion returns the major and minor version numbers of the GLX extension implemented by the server associated with connection dpy. Implementations with the same major version number are upward compatible, meaning that the implementation with the higher minor number is a superset of the version with the lower minor number. major and minor do not return values if they are specified as NULL. ERRORS
glXQueryVersion returns False if it fails, True otherwise. major and minor are not updated when False is returned. SEE ALSO
