C語言怎麽同時調用多個EXE？

不知道妳介不介意用（匿名）管道的方式來實現，通過它的轉向功能，可以很容易得到調用程序的輸出，並可進行交互。msdn中CreatePipe 函數提供了這方面的例子。還有壹個例子，當年寫bcb插件ddkbuild編譯驅動程序時寫的：

void __fastcall BuildAndMessage(AnsiString PathToBuild/*=NULL*/, AnsiString Set/*=NULL*/)

{

AnsiString CommandStr = MakeCommandStr(PathToBuild, Set);

//ShowMessage(CommandStr);

// 讀管道

HANDLE hChildStdinWr/*父進程寫*/, hChildStdinRd/*子進程讀*/;

// 寫管道

HANDLE hChildStdoutWr/*子進程寫*/, hChildStdoutRd/*父進程讀*/;

SECURITY_ATTRIBUTES sa;

_di_IOTAMessageServices MessageServices;

_di_IOTAMessageGroup MessageGroup;

if (BorlandIDEServices->Supports(MessageServices))

{

MessageServices->ClearToolMessages(NULL);

MessageGroup = MessageServices->AddMessageGroup("Ddkbuild");

MessageServices->ShowMessageView(MessageGroup);

}

else

{

ShowMessage("Create ddkbuild messageview failed");

return;

}

sa.bInheritHandle = true;

sa.lpSecurityDescriptor = NULL;

sa.nLength = sizeof(SECURITY_ATTRIBUTES);

// 創建子進程寫管道

if (!CreatePipe(&hChildStdoutRd, &hChildStdoutWr, &sa, 0))

{

ShowMessage("Create Stdout pipe failed");

return;

}

SetHandleInformation(hChildStdoutRd, HANDLE_FLAG_INHERIT, 0); // 該句柄子進程沒用到，故取消繼承性

// 創建子進程讀管道

if (!CreatePipe(&hChildStdinRd, &hChildStdinWr, &sa,0))

{

ShowMessage("Create StdinRd pipe failed");

return;

}

SetHandleInformation(hChildStdinWr, HANDLE_FLAG_INHERIT, 0); // 該句柄子進程沒用到，故取消繼承性

//SetStdHandle(STD_OUTPUT_HANDLE, hChildStdoutWr);

//SetStdHandle(STD_INPUT_HANDLE, hChildStdinRd);

PROCESS_INFORMATION pi;

STARTUPINFO si;

ZeroMemory(&si, sizeof(si));

si.cb = sizeof(STARTUPINFO);

si.dwFlags = STARTF_USESTDHANDLES | STARTF_USESHOWWINDOW;

si.wShowWindow = SW_HIDE;

si.hStdInput = hChildStdinRd; // 重定向子進程輸入

si.hStdOutput = hChildStdoutWr; // 重定向子進程輸出

si.hStdError = GetStdHandle(STD_ERROR_HANDLE);

// 註意使用了true，這樣創建子進程時，父進程的所有可繼承的句柄就可以被繼承下來了

// 我們也可以使用SetHandleInformation使句柄不可被繼承，這樣子進程就無法使用了

// 這樣的例子可以看《Creating a Child Process with Redirected Input and Output.doc》

if (!CreateProcess(NULL, CommandStr.c_str(), NULL, NULL, true, 0, NULL, NULL, &si, &pi))

{

ShowMessage("Create process failed");

return;

}

// 將數據寫入子進程，這裏只是演示，本程序不需要寫入

const char *strIn = " ";

DWORD dwBytes = 0;

WriteFile(hChildStdinWr, strIn, strlen(strIn), &dwBytes, NULL);

CloseHandle(hChildStdinWr); // 保證對端的ReadFile可返回

// 調用ReadFile前須關閉，否則因寫管道寫入端有未關閉的Write句柄，ReadFile最後無法返回0

CloseHandle(hChildStdoutWr);

// 從子進程中讀出執行結果，不處理mbcs，需要的朋友請加上前導字符的判斷

char strData[MAX_PATH * 2];

AnsiString MessageComplete, MessageCut;

char* pos;

char lf = '\n';

void* Unused = 0;

while (ReadFile(hChildStdoutRd, strData, sizeof(strData), &dwBytes, NULL))

{

strData[dwBytes] = 0;

if (pos = strrchr(strData, lf)) // 如果有換行，則顯示

{

*(pos-1) = 0;

pos++;

MessageComplete = MessageCut + strData;

MessageCut = pos;

MessageServices->AddToolMessage(

"", MessageComplete, "Ddkbuild", 0, 0, NULL, Unused, MessageGroup);

}

else // 否則暫存

MessageCut = MessageCut + strData;

Application->ProcessMessages();

}

MessageServices->AddToolMessage(

"", MessageCut, "Ddkbuild", 0, 0, NULL, Unused, MessageGroup);

// 關閉句柄

WaitForSingleObject(pi.hProcess, INFINITE);

CloseHandle(hChildStdinRd);

CloseHandle(hChildStdoutRd);

CloseHandle(pi.hProcess);

CloseHandle(pi.hThread);

}
