// Similar to TF_GraphToFunction but allows specifying control outputs of the

//
//  The arguments of TF_GraphToFunction have the same meaning, but the new
//  arguments are as follows:
//
//    ncontrol_outputs: Number of control outputs of the function.
//    control_outputs: vector of TF_Operation objects to be marked as control

// Returns the length (number of tensors) of the input argument `input_name`
// found in the provided `op`.
