Parameters

[in]	d_temp_storage	Device-accessible allocation of temporary storage. When NULL, the required allocation size is written to `temp_storage_bytes` and no work is done.
[in,out]	temp_storage_bytes	Reference to size in bytes of `d_temp_storage` allocation
[in]	d_in	Pointer to the input sequence of data items
[in]	d_flags	Pointer to the input sequence of selection flags
[out]	d_out	Pointer to the output sequence of partitioned data items
[out]	d_num_selected_out	Pointer to the output total number of items selected (i.e., the offset of the unselected partition)
[in]	num_items	Total number of items to select from
[in]	stream	[optional] hip stream to launch kernels within. Default is stream₀.
[in]	debug_synchronous	[optional] Whether or not to synchronize the stream after every kernel launch to check for errors. May cause significant slowdown. Default is `false`.
