示例1: writeBlock
/*!
\internal
Writes \a len bytes to the socket from \a data and returns the
number of bytes written. Returns -1 if an error occurred.
*/

{
// Invalid Socket -> Disconnected
if ( !socket->isValid() )
{
socket->close();
return 0;
}
if ( len == 0 )
return 0;
QByteArray* a = wba.last();
if ( a && a->size() + len < 128 )
