/**
* Sets an ndarray data element located at a specified linear index.
*
* ## Notes
*
* -   The function returns `-1` if unable to set an element and `0` otherwise.
* -   The function requires a pointer to a data value `v` in order to provide a generic API supporting ndarrays having different data types.
* -   The function has no way of determining whether `v` actually points to a memory address compatible with the underlying input ndarray data type. Accordingly, accessing **unowned** memory is possible, and this function **assumes** you know what you are doing.
