SYNOPSIS
     ##iinncclluuddee <>

     ffistatus
     ffffiipprreeppcciiff(fficif *cif, ffiabi abi, unsigned int nargs,
         ffitype *rtype, ffitype **atypes);

DESCRIPTION
     The ffffiipprreeppcciiff function prepares a ffffiicciiff structure for use with
     ffffiiccaallll or ffffiipprreeppcclloossuurree.  abi specifies a set of calling conventions
     to use.  atypes is an array of nargs pointers to ffffiittyyppee structs that
     describe the data type, size and alignment of each argument.  rtype
     points to an ffffiittyyppee that describes the data type, size and alignment of
     the return value.

RETURN VALUES
     Upon successful completion, ffffiipprreeppcciiff returns FFFFIIOOKK.  It will return
     FFFFIIBBAADDTTYYPPEEDDEEFF if cif is NNUULLLL or atypes or rtype is malformed. If abi
     does not refer to a valid ABI, FFFFIIBBAADDAABBII will be returned. Available
     ABIs are defined in <> and <>.
