receiveFd

open fun receiveFd(cancellable: Cancellable? = null): <Error class: unknown class><Int>

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.
