[Newbies] [Q] How can I write down my FFI method for this C function? (Sorry if duplicated)

Hi,

The C function is like this;

BOOL ComputeVector (int startIdx, int endIdx, double *inputSeries, int duration, int *outBeginIdx, int *outNBElement, double *outSeries);

My trial method is

apiComputeVectorWith: startIdx with: endIdx with: input duration: duration with: outBeginIdx with: outNBElement out: out <cdecl: bool 'ComputeVector' (long long double* long long* long* double*)>

But with these input variable, I got error with "could not coerce arguments".

input := ((1 to: 100) collect: [ :i | i ]) asFloatArray. startIdx := 0. endIdx := input size - 1. duration := 4. outBeginIndx := IntegerArray new: 1. outNBElement := IntegerArray new: 1. out := FloatArray new: input size. computer apiComputeVectorWith: startIdx with: endIdx with: input duration: duration with: outBeginIdx with: outNBElement out: out.

Can anyone help me on this? Thank you in advance.
