<h1>KLocalSocket Class Reference</h1>
<code>from PyKDE4.kdecore import *</code>
<p>
Inherits: QTcpSocket → QAbstractSocket → QIODevice → QObject<br />
<h2>Detailed Description</h2>
<p>KLocalSocket
KLocalSocket allows one to create and use local (Unix) sockets
</p>
<p>
On some platforms, local sockets are a kind of streaming socket
that can be used to transmit and receive data just like Internet
(TCP) streaming sockets. The difference is that they remain local
to the host running them and cannot be accessed externally. They
are also very fast and (in theory) consume less resources than
standard TCP sockets.
</p>
<p>
KLocalSocket supports two kinds of local socket types (see
KLocalSocket.LocalSocketType):
- Unix sockets (UnixSocket): standard Unix sockets whose names are
file paths and obey filesystem restrictions
- Abstract Unix sockets (AbstractUnixSocket): similar to Unix
sockets, but they don't exist as entries in the filesystem and,
thus, aren't restricted by its permissions
