I would like to pass a pointer to an array of pointers to a FFI call and I have problems ...

���I have this method:

runOutputs: aTF_OutputArray size: anInteger
������ | status outvalues |
������ status := TF_Status create.
������ outvalues := FFIExternalArray externalNewType: 'TF_Tensor*' size: anInteger.
������ self library
������ ������ runSession: self
������ ������ options: FFIExternalObject null
������ ������ inputs: FFIExternalObject null
������ ������ values: FFIExternalObject null

������ ������ count: 0
������ ������ outputs: aTF_OutputArray getHandle
������ ������ values: outvalues getHandle
������ ������ count: anInteger
������ ������ targets: FFIExternalObject null
������ ������ count: 0
������ ������ metadata: FFIExternalObject null
������ ������ status: status.
������ status check.
������ ^ outvalues

���the FFI call is like that :

runSession: aTF_Session
������ options: opsTF_Buffer
������ inputs: inTF_OutputArray values: inTF_TensorArray count: inCount
������ outputs: outTF_OutputArray values: outTF_TensorArrayPtr count: outCount
������ targets: aTF_OperationArray count: targetCount
������ metadata: metaTF_Buffer
������ status: aTF_Status
������
������ "F_CAPI_EXPORT extern void TF_SessionRun(
������ TF_Session* session,
������ // RunOptions
������ const TF_Buffer* run_options,
������ // Input tensors
������ const TF_Output* inputs, TF_Tensor* const* input_values, int ninputs,
������ // Output tensors
������ const TF_Output* outputs, TF_Tensor** output_values, int noutputs,
������ // Target operations
������ const TF_Operation* const* target_opers, int ntargets,
������ // RunMetadata
������ TF_Buffer* run_metadata,
������ // Output status
������ ��TF_Status*);"
������ ������
������ ������ ^ self
������ ������ ffiCall: #(void TF_SessionRun #(TF_Session * aTF_Session, TF_Buffer * opsTF_Buffer, TF_Output * inTF_OutputArray, TF_Tensor * inTF_TensorArray, int inCount, TF_Output * outTF_OutputArray, TF_Tensor * outTF_TensorArrayPtr, int outCount, TF_Operation * aTF_OperationArray, int targetCount, TF_Buffer * metaTF_Buffer, TF_Status * aTF_Status))
������ ������ module: TensorFlowCAPI

TF_Tensor is an opaque object.

I have an error: "Could not coerce arguments".

I guess this is related to the way I pass arguments to the FFI function ?
