網路編程源碼
A. unix 網路編程源碼按照README make 執行後生成了.o 的文件，之後如何運行這些文件呢
簡單來說，c語言是編譯語言，所有源代碼都需要編譯後才能形成可執行文件
編譯語言第一步，是把源代碼.c文件編譯成目標文件.o，目標文件時中間文件，不能夠執行。這步主要是驗證每個單獨的.c文件，是否在自己內部有語法錯誤，然後再通過鏈接（即link），把目標文件串起來，形成可執行文件（默認.out後綴）。

C. 怎麼到圖靈網站下載unix網路編程源碼
打開網頁http://www.turingbook.com/Homepage/Default.aspx
這是圖靈的主頁，然後在搜索里搜 unix網路編程
在頁面中點擊 資源下載
...
只需要免費注冊一下即可。
怕你不懂
我把第一卷和第二卷的下載網址給你貼在下面了
http://www.turingbook.com/BookResources/ListBookResource.aspx?BookID=575

D. 關於java網路編程的基礎問題，已經附帶源代碼
你需要用一個list 管理 所有的客戶端socket 。
Socket socket = ss.accept();
socketList.add(socket )
然後 再依次向么個socket 輸出
for (Iterator iterator = socketList.iterator(); iterator.hasNext();) {
Socket object = (Socket) iterator.next();
OutputStream os = socket.getOutputStream();
DataOutputStream dis = new DataOutputStream(os);
dis.writeUTF( 「message」);
}
E. asp源碼/網路編程
if Request.QueryString("link")<>"" then '如果link參數不為空值
linkpath=Request.ServerVariables("Query_String") '獲得所有參數字串即"?"後面的部分,如xxx.asp?a=1&b=2 linkpath的值就是a=1&b=2
pos=Instr(linkpath,"link=") '獲得 字串 link= 在linkpath中的位置
linkpath=right(linkpath,len(Request.ServerVariables("Query_String"))-pos-4)
'len(Request.ServerVariables("Query_String"))-pos-4 '獲得 字串 link以後的字串,包含link 然後-4 得到=的距左的位置,再Rigth取得=後邊的字串
Response.Redirect(linkpath) '瀏覽器轉向
else
Response.Redirect("main.asp") '同上
end if
寫這代碼的人閑的? 得到的結果就相當於Request.QueryString("link")的值
等同以下代碼
if Request.QueryString("link")<>"" then
Response.Redirect(Request.QueryString("link"))
else
Response.Redirect("main.asp")
end if
F. unix網路編程的源碼是c的還是c++的
是Richard stevens那本嗎？是C語言的，UNIX的系統調用也是C定義的。
懷念Richard stevens大師。
