GLXQUERYEXTENSION()													       GLXQUERYEXTENSION()

NAME

       glXQueryExtension - indicate whether the GLX extension is supported

C SPECIFICATION

       Bool glXQueryExtension( Display *dpy,
			       int *errorBase,
			       int *eventBase )

       delim $$

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.  Otherwise, errorBase and eventBase are unchanged.

       errorBase and eventBase do not return values if they are specified as NULL.

NOTES

       eventBase is included for future extensions.  GLX does not currently define any events.

NAME

       glXQueryServerString - return string describing the server

C SPECIFICATION

       const char * glXQueryServerString(Display * dpy, int screen, int name);

PARAMETERS

       dpy
	   Specifies the connection to the X server.

       screen
	   Specifies the screen number.

       name
	   Specifies which string is returned: one of GLX_VENDOR, GLX_VERSION, or GLX_EXTENSIONS.

DESCRIPTION

       glXQueryServerString returns a pointer to a static, null-terminated string describing some aspect of the server's GLX extension. The
       possible values for name and the format of the strings is the same as for glXGetClientString(). If name is not set to a recognized value,
       NULL is returned.

NOTES

       glXQueryServerString is available only if the GLX version is 1.1 or greater.

       If the GLX version is 1.1 or 1.0, the GL version must be 1.0. If the GLX version is 1.2, the GL version must be 1.1. If the GLX version is
       1.3, the GL version must be 1.2.

       glXQueryServerString only returns information about GLX extensions supported by the server. Call glGetString() to get a list of GL
       extensions. Call glXGetClientString() to get a list of GLX extensions supported by the client.
