Parameters
[in]d_temp_storageDevice-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_bytesReference to size in bytes of d_temp_storage allocation
[in]d_inPointer to the input sequence of data items
[in]d_flagsPointer to the input sequence of selection flags
[out]d_outPointer to the output sequence of partitioned data items
[out]d_num_selected_outPointer to the output total number of items selected (i.e., the offset of the unselected partition)
[in]num_itemsTotal 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.
