GLXQUERYSERVERSTRING()													    GLXQUERYSERVERSTRING()

NAME

       glXQueryServerString - return string describing the server

C SPECIFICATION

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

       delim $$

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 possi-
       ble 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.

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

NAME

       glXGetClientString - return a string describing the client

C SPECIFICATION

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

PARAMETERS

       dpy
	   Specifies the connection to the X server.

       name
	   Specifies which string is returned. The symbolic constants GLX_VENDOR, GLX_VERSION, and GLX_EXTENSIONS are accepted.

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
       spaces.) 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. If the GLX
       version is 1.3, then the GL version must be 1.2.

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