solaris中bind为何失败

gulu

程序如下： \r\n端口没有被占用！ \r\n\r\nsockaddr_in ListenAddr; \r\n\r\nSocketId = socket (AF_INET, SOCK_STREAM, 0); \r\nif (SocketId < 0) \r\nreturn false; \r\n\r\nmemset (&ListenAddr, 0, sizeof (ListenAddr)); \r\nListenAddr.sin_family = AF_INET; \r\nListenAddr.sin_port = htons (4000); \r\nListenAddr.sin_addr.s_addr = htonl (INADDR_ANY); \r\n\r\nif ( bind (SocketId, (struct sockaddr *) &ListenAddr, sizeof ListenAddr))) \r\ngoto error_parse; \r\n\r\nif (listen (SocketId, BackLog)) \r\ngoto error_parse; \r\nreturn true; \r\n\r\nerror_parse: \r\nclose(SocketId); \r\nreturn false;
