ffi_prep_cif_var (3)

Name

ffi_prep_cif_var - Prepare a ffi_cif structure for use with ffi_call for variadic functions.

Synopsis

#include <ffi.h>

ffi_status
ffi_prep_cif_var(ffi_cif *cif, ffi_abi abi, unsigned int nfixedargs,
unsigned int ntotalargs, ffi_type *rtype, ffi_type **atypes);

Description

ffi_prep_cif_var(3)      BSD Library Functions Manual      ffi_prep_cif_var(3)

NAME
     ffi_prep_cif_var -- Prepare a ffi_cif structure for use with ffi_call for
     variadic functions.

SYNOPSIS
     #include <ffi.h>

     ffi_status
     ffi_prep_cif_var(ffi_cif *cif, ffi_abi abi, unsigned int nfixedargs,
         unsigned int ntotalargs, ffi_type *rtype, ffi_type **atypes);

DESCRIPTION
     The ffi_prep_cif_var function prepares a ffi_cif structure for use with
     ffi_call for variadic functions.  abi specifies a set of calling conven-
     tions to use.  atypes is an array of ntotalargs pointers to ffi_type
     structs that describe the data type, size and alignment of each argument.
     rtype points to an ffi_type that describes the data type, size and align-
     ment of the return value.  nfixedargs must contain the number of fixed
     (non-variadic) arguments.  Note that to call a non-variadic function
     ffi_prep_cif must be used.

RETURN VALUES
     Upon successful completion, ffi_prep_cif_var returns FFI_OK.  It will
     return FFI_BAD_TYPEDEF if cif is NULL or atypes or rtype is malformed. If
     abi does not refer to a valid ABI, FFI_BAD_ABI will be returned. Avail-
     able ABIs are defined in <ffitarget.h>
