在dos下

假設我現在要呼叫一個叫svm-train.exe的檔案

之後會傳參數給他如下 svm-train -v 5 -c 10 heart_scale

請問在c如何完成它"-v 5 -c 10 heart_scale"參數

若是Turbo C 2.0 或以上，請使用function
int execl(char *path, char *arg0 *arg1, ..., *argn, NULL);

此fucntion非ANSI C標準。若你的c complier沒suport…問題就大一點，不過我想應該是都有。

再不然就呼叫DOS中斷服務程式(相當於windows的api):
使用服務4Ah，將父記憶體縮小以空出空間給子程序跑，再來使用4B00h服務，將子程序檔名指向ds:dx的位址，再將參數設定成PCB結構體4個位址共14bytes，然後將es:bx指向這個結構位址…

好懷念dos時代…應該很少人寫dos的程式了吧?!

謝謝你的答覆^^

雖然真的不太懂你的寫法

不過還是很感謝

順便一問

請問你知道winexec的使用方式嗎?

他可以傳值?

真的很感謝你的答覆

首先關於我指的dos 如你所說

是dos box 我不會寫dos的程式^^"

很感謝你針對ㄅwinexec() function的解釋

不過有一點小疑問再請教

第一個部份我們是以檔案位置 參數

那,後那是指輸出的格式嗎?

我可以選擇讓他讀入檔案?

小弟再次感謝您詳細的回答

後面的參數SW_SHOWNORMAL是指你要執行的那程式在被開啟的時候是呈現怎樣的狀態，比如說我下的這個參數是指用一般的方式展現，也可以是下面的幾種，我貼msdn的給你看看，自行參考吧:

SW_FORCEMINIMIZE

Windows 2000/XP: Minimizes a window, even if the thread that owns the window is not responding. This flag should only be used when minimizing windows from a different thread.

SW_HIDE

Hides the window and activates another window.

SW_MAXIMIZE

Maximizes the specified window.

SW_MINIMIZE

Minimizes the specified window and activates the next top-level window in the Z order.

SW_RESTORE

Activates and displays the window. If the window is minimized or maximized, the system restores it to its original size and position. An application should specify this flag when restoring a minimized window.

SW_SHOW

Activates the window and displays it in its current size and position.

SW_SHOWDEFAULT

Sets the show state based on the SW_ value specified in the STARTUPINFO structure passed to the CreateProcess function by the program that started the application.

SW_SHOWMAXIMIZED

Activates the window and displays it as a maximized window.

SW_SHOWMINIMIZED

Activates the window and displays it as a minimized window.

SW_SHOWMINNOACTIVE

Displays the window as a minimized window. This value is similar to SW_SHOWMINIMIZED, except the window is not activated.

SW_SHOWNA

Displays the window in its current size and position. This value is similar to SW_SHOW, except the window is not activated.

SW_SHOWNOACTIVATE

Displays a window in its most recent size and position. This value is similar to SW_SHOWNORMAL, except the window is not actived.

SW_SHOWNORMAL

Activates and displays a window. If the window is minimized or maximized, the system restores it to its original size and position. An application should specify this flag when displaying the window for the first time.
