PARAMETERS
       error  Specifies a GL or GLU error code.

DESCRIPTION
       gluErrorString produces an error string from a GL or GLU error code. The
       string  is  in  ISO  Latin  1  format.  For  example,   gluErrorString(‐
       GL_OUT_OF_MEMORY) returns the string out of memory.

       The  standard  GLU  error codes are GLU_INVALID_ENUM, GLU_INVALID_VALUE,
       and GLU_OUT_OF_MEMORY.  Certain other GLU functions can return  special‐
       ized  error  codes through callbacks.  See the glGetError reference page
       for the list of GL error codes.

ERRORS
       NULL is returned if error is not a valid GL or GLU error code.
