forbids declaration of `tcpBind' with no type

ANSI C++ forbids declaration of `tcpBind' with no type

CTcpTrans::tcpBind(int sockfd, struct sockaddr *my_addr, int addrlen)
{
    int ret;
   
    ret = bind(sockfd, my_addr, addrlen);
   
    return ret;
}
改为
int CTcpTrans::tcpBind(int sockfd, struct sockaddr *my_addr, int addrlen)
{
    int ret;
   
    ret = bind(sockfd, my_addr, addrlen);
   
    return ret;
}
函数前面要加类型。
