/* Fortran API wrappers, using the F77 macro defined in f77api.c.
   This header file is #included one or more times from f77api.c
   in order to define verions of the Fortran API for various compilers. 

   All of the functions in this file have underscores in their names,
   which means that they are treated differently for name-mangling
   (thank you, g77 and f2c) than names without underscores.
   
   The return value of a function is converted to the first argument
   of a subroutine. */
