我编写了一个简单的程序,它读取来自stdin的输入并通过TCP发送到一个监听端口15557的服务器。当我在Linux下编译和运行它时,它工作得很好。但是,当我试图在Cygwin下编译和运行它时,它会失败,出现以下错误消息: $ ./a.out servername.net 15557 < test.dat Unable to connect: Cannot assign requested address...

此数据结构用做bind、connect、recvfrom、sendto等函数的参数,指明地址信息。 但一般编程中并不直接针对此数据结构操作,而是使用另一个与sockaddr等价的数据结构 sockaddr_in(在netinet/in.h中定义): struct sockaddr_in { short int sin_family; /* Address family */ ...
