Copy state vector elements to an external buffer.

Parameters

handle (intptr_t) – the handle to the cuStateVec library.
accessor (intptr_t) – the accessor descriptor.
external_buffer (intptr_t) – pointer to a host or device buffer to receive copied elements.
begin (int64_t) – index in the permuted bit ordering for the first elements being copied to the state vector.
end (int64_t) – index in the permuted bit ordering for the last elements being copied to the state vector (non-inclusive).
