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.

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.
