Function Documentation

◆ sendme_circuit_consider_sending()

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.

Definition at line 418 of file sendme.c.

◆ 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.
