pub unsafe extern "C" fn q_conn_send(
poll: *mut ray_poll_t,
id: i64,
msg: *mut ray_t,
) -> *mut ray_tExpand description
Sync round-trip on an attached connection: write a SYNC frame, then pump
this connection until its RESPONSE arrives — dispatching, not swallowing,
any frame that arrives in between. So a bound handler can fire before
this returns. Returns a freshly-owned object, possibly a RAY_ERROR.
Refuses a nested call from inside a handler.
