DESCRIPTION
ggllXXQQuueerryyEExxtteennssiioonn returns TTrruuee if the X server of
connection _d_p_y supports the GLX extension,
FFaallssee otherwise.
If TTrruuee is returned,
then _e_r_r_o_r_B_a_s_e and _e_v_e_n_t_B_a_s_e return the error base and event base of
the GLX extension.
Otherwise, _e_r_r_o_r_B_a_s_e and _e_v_e_n_t_B_a_s_e are unchanged.
_e_r_r_o_r_B_a_s_e and _e_v_e_n_t_B_a_s_e do not return values if they are specified
as NNUULLLL.
NOTES
_e_v_e_n_t_B_a_s_e is included for future extensions.
GLX does not currently define any events.
