# BNNSGraphGetArgumentInterleaveFactors(_:_:_:_:_:) Returns the interleave factors for arguments, if present ``` func BNNSGraphGetArgumentInterleaveFactors(_ graph: bnns_graph_t, _ function: UnsafePointer?, _ argument_count: Int, _ argument_interleave: UnsafeMutablePointer?>, _ argument_interleave_counts: UnsafeMutablePointer) -> Int32 ``` ## 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`. --- Copyright © 2026 Apple Inc.
