Ns_SockCloseLater

Overview

Close a remote connection which has not yet timed out.

Syntax

    int Ns_SockCloseLater (
    	SOCKET			sock
    );

Description

Ns_SockCloseLater can be used to have the socket service thread close a socket which has yet to timeout after an Ns_SockAsyncConnect.

Example

    SOCKET sock;
    fd_set set;
    struct timeval tv;
    sock = Ns_SockAsyncConnect("mailhost", 25);
    ... perform some other work while connection is in progress...
    
    ... check for connection ...
    tv.tv_sec = 2; /* allow 2 more seconds */
    tv.tv_usec = 0;
    FD_ZERO(&set);
    FD_SET(sock, &set);
    if (select(sock+1, NULL, &set, NULL, &tv) != 1) {
       ... timeout - close socket and return error...
       Ns_CloseLater(sock); 
    } else {
       ... use socket ...
    }
