GLXGETCLIENTSTRING()													      GLXGETCLIENTSTRING()

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.

NAME

       gluCheckExtension - determines if an extension name is supported

C SPECIFICATION

       GLboolean gluCheckExtension(const GLubyte * extName, const GLubyte * extString);

PARAMETERS

       extName
	   Specifies an extension name.

       extString
	   Specifies a space-separated list of extension names supported.

DESCRIPTION

       gluCheckExtension returns GLU_TRUE if extName is supported otherwise GLU_FALSE is returned.

       This is used to check for the presence for OpenGL, GLU, or GLX extension names by passing the extension strings returned by glGetString(),
       gluGetString(), glXGetClientString(), glXQueryExtensionsString(), or glXQueryServerString(), respectively, as extString.

NOTES

       Cases where one extension name is a substring of another are correctly handled.

       There may or may not be leading or trailing blanks in extString.

       Extension names should not contain embedded spaces.

       All strings are null-terminated.
