func (*Client) RegisterPTYSession added in v0.7.35 

func (c *Client) RegisterPTYSession(ctx context.Context, sessionID string) (write PTYWriteFunc, input <-chan []byte, cleanup func())

RegisterPTYSession creates an input channel for a reclaimed session so pty.attach/input/resize/kill messages from the relay get routed to it. Returns the input channel and a write function. The caller must start a goroutine to handle the session and clean up when done.
