GLXQUERYVERSION()														 GLXQUERYVERSION()

NAME

       glXQueryVersion - return the version numbers of the GLX extension

C SPECIFICATION

       Bool glXQueryVersion( Display *dpy,
			     int *major,
			     int *minor )

       delim $$

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

       glXGetClientString - return a string describing the client

C SPECIFICATION

       const char * glXGetClientString( Display *dpy,
					int name )

       delim $$

PARAMETERS

       dpy   Specifies the connection to the X server.

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

DESCRIPTION

       glXGetClientString returns a string describing some aspect of the client library. The possible values for name are GLX_VENDOR, GLX_VERSION,
       and GLX_EXTENSIONS. If name is not set to one of these values, glXGetClientString returns NULL.	The format  and  contents  of  the  vendor
       string is implementation dependent.

       The  extensions	string is null-terminated and contains a space-separated list of  extension names. (The extension names never contain spa-
       ces.)  If there are no extensions to GLX, then the empty string is returned.

       The version string is laid out as follows:

       <major_version.minor_version><space><vendor-specific info>

       Both the major and minor portions of the version number are of arbitrary length.  The vendor-specific information is optional.  However, if
       it is present, the format and contents are implementation specific.

NOTES

       glXGetClientString 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, then the GL version must be 1.1.

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