This class implements the message communication using function calls directly.
<p>
It can only be used when both sides of the message pipe are within the same process. The communication is very fast.<p>
To establish a communication, you have to create two instances of <a class="el" href="classKMessageDirect.html" title="This class implements the message communication using function calls directly.">KMessageDirect</a>, the first one with no parameters in the constructor, the second one with the first as parameter:<p>
/code <a class="el" href="classKMessageDirect.html" title="This class implements the message communication using function calls directly.">KMessageDirect</a> *peer1, *peer2; peer1 = new <a class="el" href="classKMessageDirect.html" title="This class implements the message communication using function calls directly.">KMessageDirect</a> (); // unconnected peer2 = new <a class="el" href="classKMessageDirect.html" title="This class implements the message communication using function calls directly.">KMessageDirect</a> (peer1); // connect with peer1 /endcode<p>
The connection is only closed when one of the instances is deleted.
