以下

let new_socket () = Lwt_unix.socket Unix.PF_INET Unix.SOCK_STREAM 0 in  
let socket_address = Network.make_address "127.0.0.1" 7777 in  
let listening_socket = new_socket () in  
Lwt_unix.setsockopt listening_socket Unix.SO_REUSEADDR true;  
Lwt_unix.bind listening_socket socket_address; 

导致此错误:

错误:正确性:2:remote_client:0:设置

Unix.Unix_error(Unix.EADDRINUSE, "bind", "")
Raised at file "src/core/lwt.ml", line 782, characters 22-23
Called from file "src/unix/lwt_main.ml", line 34, characters 8-18
Called from file "src/oUnit.ml", line 597, characters 6-10`

最后一行未能授予绑定,想法原因,如何通过?

1 个答案:

答案 0 :(得分:3)

错误已明确说明:您尝试绑定的地址已在使用中,套接字已绑定在端口7777上。

要了解函数的Unix_error代码,请查看相应C unix函数的手册,在这种情况下bind(2)
