# BNNSGraphGetArgumentInterleaveFactors(_:_:_:_:_:)

Returns the interleave factors for arguments, if present

## Declaration

```swift
func BNNSGraphGetArgumentInterleaveFactors(_ graph: bnns_graph_t, _ function: UnsafePointer<CChar>?, _ argument_count: Int, _ argument_interleave: UnsafeMutablePointer<UnsafePointer<UInt16>?>, _ argument_interleave_counts: UnsafeMutablePointer<Int>) -> Int32
```

## Discussion

Discussion If any arguments to the function are specified with an interleave factor (e.g. using the interleave option to tensor_buffer in MIL), this function can be used to retrieve the interleave factor array. Arguments: graph: object to query. function: function to query. It may be NULL if there is only one function. argument_count: number of elements in argument_interleave and in argument_interleave_counts. argument_interleave: array of pointers to interleave factors to populate. On exit argument_interleave[i] will be set to either: NULL if argument i has no interleave factor; or a pointer into the graph object containing the interleave factors that contains argument_interleave_counts[i] elements. Only the first [0, min(argument_count, argument_interleave)) entries are set. argument_interleave_counts: gives the size of the array pointed to by argument_interleave[i], or is set to 0 if argument_interleave[i] is set to NULL. Returns: 0 on success, nonzero on failure. Failure may be caused by either invalid values of graph or function.
