GioUnixConnectionsend_fd

Declaration

g_unix_connection_send_fd (
  GUnixConnection* connection,
  gint fd,
  GCancellable* cancellable,
  GError** error
)

Description

Passes a file descriptor to the receiving side of the connection. The receiving end has to call g_unix_connection_receive_fd() to accept the file descriptor.

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