Fortune Server example

[babu198649]

hi
in the fortune server example i need a explanation for the below statement

out << (quint16)(block.size() - sizeof(quint16));

out << (quint16)(block.size() - sizeof(quint16));

To copy to clipboard, switch view to plain text mode 

which is inside the void Server::sendFortune() function.

which can be found at the following url
http://doc.trolltech.com/4.3/network...erver-cpp.html

while we need the size of the block to be specified at the first two bytes
why the size of the block is subtracted with the 2bytes(i.e quint16) .

bye
