Function gnunet_sys::GNUNET_MQ_impl_state

pub unsafe extern "C" fn GNUNET_MQ_impl_state(
    mq: *mut GNUNET_MQ_Handle
) -> *mut c_void

Get the implementation state associated with the message queue.

While the GNUNET_MQ_Impl* callbacks receive the implementation state, continuations that are scheduled by the implementation function often only have one closure argument, with this function it is possible to get at the implementation state when only passing the struct GNUNET_MQ_Handle as closure.

@param mq message queue with the current message @return message to send, never NULL
