The LINGER structure has the following form:
struct linger {
u_short l_onoff; // option on/off
u_short l_linger; // linger time
};
The LINGER structure is used for manipulating the SO_LINGER and SO_DONTLINGER options of CAsyncSocket::GetSockOpt.
Comments
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.
