SYNOPSIS:
How to provide timeout for read operation in ACE_IOStream?


DESCRIPTION:
By using ACE_IOSTREAM there is a needs having timeout for read operation if methode eof has been used. Member recv_timeout_value_ could be set by using methode recv_timeout(ACE_Time_Value *tv) but I have not access to the underlying STREAM (ACE_Streambuf).
Example as following:

ACE_IOStream<ACE_SOCK_Stream> server;
// preparing IP connection object
ACE_SOCK_Connector connector;
ACE_INET_Addr addr( iPort, sIp.c_str() );

if( connector.connect( server, addr ) )
{
char c = 0;
while( !server.eof() )
{
server.recv( &c, 1 );
// do something
}
}
server.close();

There is an extract operator given but I don't know how to use it.
ACE_IOStream<STREAM> & operator>> (ACE_Time_Value *&tv);
