UnixConnection.receiveFd

int receiveFd(gio.cancellable.Cancellable cancellable = null)

Receives a file descriptor from the sending end of the connection. The sending end has to call [gio.unix_connection.UnixConnection.sendFd] for this to work.

As well as reading the fd this also reads a single byte from the stream, as this is required for fd passing to work on some implementations.
