   GLboolean
    glIsFramebuffer(GLuint   framebuffer  );  
 
  PARAMETERS  
   framebuffer  
 Specifies a value that may be the name of a framebuffer
  object. 
 
  DESCRIPTION  
   glIsFramebuffer  returns  GL_TRUE  if
     framebuffer  is currently the name of a framebuffer object. If
     framebuffer  is zero, or if  framebuffer  is not the name of a
    framebuffer object, or if an error occurs,  glIsFramebuffer  returns
     GL_FALSE . If  framebuffer  is a name returned by
     glGenFramebuffers (), by that has not yet been bound through a call to
     glBindFramebuffer (), then the name is not a framebuffer object and
     glIsFramebuffer  returns  GL_FALSE .
