Inheritance diagram for LocalChannel:

Public Member Functions
	LocalChannel ()
	Create a local socket communication channel.
Public Member Functions inherited from IoChannel
	IoChannel ()=default
	Create a null I/O channel.
int	slaveFd () const
	Communication end of the sub-process.
Public Member Functions inherited from IoStream
	IoStream ()=default
	Create a null I/O stream.
	IoStream (int fd)
	Create an I/O stream for file descriptor fd.
int	fd () const

void	duplicateTo (IoStream &other)
	Duplicate this I/O stream.
IoStream	duplicate () const
	Duplicate I/O stream other.
bool	isInteractive () const
	Check if this is a teletype (e.g.
void	echo (bool on)
	Set echo mode of this I/O stream to on
int	ioctl (int request, void *arg)
	Issue an device control request.
