LINGER Structure

The LINGER structure is used for manipulating the SO_LINGER and SO_DONTLINGER options of CAsyncSocket::GetSockOpt.

struct linger { 
   u_short l_onoff;            // option on/off 
   u_short l_linger;           // linger time 
};

Setting the SO_DONTLINGER option prevents blocking on member function Close while waiting for unsent data to be sent. Setting this option is equivalent to setting SO_LINGER with l_onoff set to 0.
