| void sendme_circuit_consider_sending | ( | circuit_t * | circ, |
| crypt_path_t * | layer_hint ) |
Check if the deliver_window for circuit circ (at hop layer_hint if it's defined) is low enough that we should send a circuit-level sendme back down the circuit. If so, send enough sendmes that the window would be overfull if we sent any more.

◆ sendme_connection_edge_consider_sending()
| void sendme_connection_edge_consider_sending | ( | edge_connection_t * | conn | ) |
Called when we've just received a relay data cell, when we've just finished flushing all bytes to stream conn, or when we've flushed some bytes to the stream conn.
If conn->outbuf is not too full, and our deliver window is low, send back a suitable number of stream-level sendme cells.
