Declaration [src] 

GIOStream*
download (
  ValentChannel* channel,
  JsonNode* packet,
  GCancellable* cancellable,
  GError** error
)

Description [src]

Open an auxiliary connection, usually to download data.

Implementations should use information from the payloadTransferInfo field to open a connection and wait for it to be accepted. In most cases the remote device will write data to the stream and then close it when finished.

For example, a TCP-based implementation could connect to a port in the payloadTransferInfo dictionary on the same host as the channel. When the connection is accepted the caller can perform operations on it as required.
