Function grpcio_sys::grpc_completion_queue_pluck

pub unsafe extern "C" fn grpc_completion_queue_pluck(
    cq: *mut grpc_completion_queue,
    tag: *mut c_void,
    deadline: gpr_timespec,
    reserved: *mut c_void
) -> grpc_event

Blocks until an event with tag ‘tag’ is available, the completion queue is being shutdown or deadline is reached.

Returns a grpc_event with type GRPC_QUEUE_TIMEOUT on timeout, otherwise a grpc_event describing the event that occurred.

Callers must not call grpc_completion_queue_next and grpc_completion_queue_pluck simultaneously on the same completion queue.

Completion queues support a maximum of GRPC_MAX_COMPLETION_QUEUE_PLUCKERS concurrently executing plucks at any time.
