To zhaolaoxin 感谢回答问题。 我以前是这样,将服务器的IP写在客户端保存,用在局域网,Socket联接,定义了一个端口。现在准备用在广域网,可以直接把域名写在原来IP的文本框中就可以了吗?
gethostbyname The gethostbyname function retrieves host information corresponding to a host name from a host database.Note The gethostbyname function has been deprecated by the introduction of the getaddrinfo function. Developers creating Windows Sockets 2 applications are urged to use the getaddrinfo function instead of gethostbyname. struct hostent* FAR gethostbyname( const char* name );Parameters name [in] Pointer to the null-terminated name of the host to resolve.
