Function dqcsim::bindings::dqcs_sim_arb_idx

#[no_mangle]pub extern "C" fn dqcs_sim_arb_idx(
    sim: dqcs_handle_t, 
    index: ssize_t, 
    cmd: dqcs_handle_t
) -> dqcs_handle_t

Sends an ArbCmd message to one of the plugins, referenced by index.

The frontend always has index 0. 1 through N are used for the operators in front to back order (where N is the number of operators). The backend is at index N+1.

Python-style negative indices are supported. That is, -1 can be used to refer to the backend, -2 to the last operator, and so on.

ArbCmds are executed immediately after yielding to the simulator, so all pending asynchronous calls are flushed and executed before the ArbCmd.

When this succeeds, the received data is returned in the form of a new handle. When it fails, 0 is returned.

The ArbCmd handle is consumed if and only if the API call succeeds.
