# xpc_array_get_data(_:_:_:) Gets a pointer to the raw bytes of a data object from an array directly. ``` func xpc_array_get_data(_ xarray: xpc_object_t, _ index: Int, _ length: UnsafeMutablePointer?) -> UnsafeRawPointer? ``` ## Parameters `xarray` The array which is to be examined. `index` The index of the value to obtain. This value must lie within the index space of the array (0 to N-1 inclusive, where N is the count of the array). If the index is outside that range, the behavior is undefined. `length` Upon return output, will contain the length of the data corresponding to the specified key. ## Return Value The underlying bytes at the specified index. NULL if the value at the specified index is not a data value. --- Copyright © 2026 Apple Inc.
