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> ATTRIBUTES See attributes(7) for descriptions of the following attributes: +---------------+------------------+ |ATTRIBUTE TYPE | ATTRIBUTE VALUE | +---------------+------------------+ |Availability | library/libffi | +---------------+------------------+ |Stability | Uncommitted | +---------------+------------------+ SEE ALSO ffi(3), ffi_call(3), ffi_prep_cif(3) NOTES Source code for open source software components in Oracle Solaris can be found at https://www.oracle.com/downloads/opensource/solaris-source-code- downloads.html.
