receiveFd
open fun receiveFd(cancellable: Cancellable? = null): <Error class: unknown class><<Error class: unknown class>>
Receives a file descriptor from the sending end of the connection. The sending end has to call g_unix_connection_send_fd() 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.
Return
a file descriptor on success, -1 on error.

2.22
Parameters
