*  Name:
*     fellipse.c

*  Purpose:
*     Define a FORTRAN 77 interface to the AST Ellipse class.

*  Type of Module:
*     C source file.

*  Description:
*     This file defines FORTRAN 77-callable C functions which provide
*     a public FORTRAN 77 interface to the Ellipse class.

*  Routines Defined:
*     AST_ISAELLIPSE
*     AST_ELLIPSE
