GLUCHECKEXTENSION(3G)                                    GLUCHECKEXTENSION(3G)



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 sup-
                  ported.

DESCRIPTION
       gluCheckExtension returns GLTRUE if  extName  is  supported  otherwise
       GLFALSE 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  glX-
       QueryServerString, 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.
