我目前有一個套接字源。但有些事情對終端來說是錯誤的。當我寫的gcc http_client.c或使http_client我得到這個錯誤:C Socket:error:expected')'in'&'token in inet_aton();
http_client.c: In function ‘main’:
http_client.c:24:25: error: expected ‘)’ before ‘&’ token
int inet_aton(address, &remote_address.sin_addr.s_addr);
和
In file included from http_client.c:9:0:
/usr/include/arpa/inet.h:73:12: note: expected ‘struct in_addr *’ but
argument is of type ‘in_addr_t * {aka unsigned int *}’
extern int inet_aton (const char *__cp, struct in_addr *__inp) __THROW;
但由http_client和終端說我「分段錯誤(核心轉儲)」我曾嘗試很多方面,只是沒有。我該如何解決這個錯誤?
編輯:當我寫./http_client 216.239.38.120有一些命令:

recv(client_socket, &response, sizeof(response), 0);
printf("Response from the server: %s\n", response);
close(client_socket);

}
原諒我的錯誤的語言。
我爲socket編程初學者我C.所以,這個地址,和罪惡命令讓我迷惑的任何時間。我沒有嘗試過。謝謝,它爲我工作。 –
我們都必須從某個地方開始,很高興我能提供幫助。 – Nunchy
我很抱歉,但是,使命令成功工作。 ./http_client 216.239.38.120正在工作。但我懷疑它,因爲當我運行這個命令時,終端必須給我expires,cache-control,server,x-xss,x-frame等命令。我錯了嗎?簡單的信息;這個客戶端使用我的http_server.c源代碼?在這個源文件中有一個char http_header [2048] =「HTTP/1.1 200 OK \ r \ n \ n」;和終端顯示來自服務器的響應:HTTP/1.1 302 Found。我非常困惑 –
