如何在Windows上的C中的CreateProcess执行Python脚本？

我已经成功地在C代码中使用PIPES在Unix上获得调用Python脚本的C代码。 我现在需要在Windows上做同样的事情。

基本上我想在不同的脚本语言如Python / Lua等在Windows上编写脚本，并能够使用STDIN / STDOUT等来执行它们。

我一直在看“CreateProcess”调用：

• 单个exe文件可更改的设置
• testing一个文件/目录是只读的
• 在Windows上，我们如何将虚拟键码转换为移位字符？
• Windows轮询或select命名pipe道
• 在Python中运行时在记事本中打开一个string

尽pipe我可以用“用C编写的孩子”来工作，但我无法调用Python脚本。

以下是我的窗口框中的“父/发件人代码”：

#include<windows.h> #include <stdio.h> #include <stdlib.h> #pragma comment(lib, "User32.lib") void DisplayError(char *pszAPI); void readFromPipe(HANDLE hPipeRead); void createChildProcess(char *commandLine, HANDLE hChildStdOut, HANDLE hChildStdIn, HANDLE hChildStdErr); DWORD WINAPI writeToPipe(LPVOID lpvThreadParam); HANDLE hChildProcess = NULL; HANDLE hStdIn = NULL; BOOL bRunThread = TRUE; char *inputStream; int main(int argc, char *argv[]){ HANDLE hOutputReadTmp,hOutputRead,hOutputWrite; HANDLE hInputWriteTmp,hInputRead,hInputWrite; HANDLE hErrorWrite; HANDLE hThread; DWORD ThreadId; SECURITY_ATTRIBUTES sa; int streamLen; sa.nLength= sizeof(SECURITY_ATTRIBUTES); sa.lpSecurityDescriptor = NULL; sa.bInheritHandle = TRUE; if (!CreatePipe(&hOutputReadTmp,&hOutputWrite,&sa,0)) return 1; if (!DuplicateHandle(GetCurrentProcess(),hOutputWrite, GetCurrentProcess(),&hErrorWrite,0, TRUE,DUPLICATE_SAME_ACCESS)) return 1; if (!CreatePipe(&hInputRead,&hInputWriteTmp,&sa,0)) return 1; if (!DuplicateHandle(GetCurrentProcess(),hOutputReadTmp, GetCurrentProcess(), &hOutputRead, 0,FALSE, DUPLICATE_SAME_ACCESS)) return 1; if (!DuplicateHandle(GetCurrentProcess(),hInputWriteTmp, GetCurrentProcess(), &hInputWrite, 0,FALSE, DUPLICATE_SAME_ACCESS)) return 1; if (!CloseHandle(hOutputReadTmp)) return 1;; if (!CloseHandle(hInputWriteTmp)) return 1;; if ( (hStdIn = GetStdHandle(STD_INPUT_HANDLE)) == INVALID_HANDLE_VALUE ) return 1; if (argc == 2){ createChildProcess(argv[1], hOutputWrite,hInputRead,hErrorWrite); }else{ puts("No process name / input stream specified\n"); return 1; } if (!CloseHandle(hOutputWrite)) return 1;; if (!CloseHandle(hInputRead )) return 1;; if (!CloseHandle(hErrorWrite)) return 1;; hThread = CreateThread(NULL,0,writeToPipe, (LPVOID)hInputWrite,0,&ThreadId); if (hThread == NULL) return 1;; readFromPipe(hOutputRead); if (!CloseHandle(hStdIn)) return 1; bRunThread = FALSE; if (WaitForSingleObject(hThread,INFINITE) == WAIT_FAILED) return 1;; if (!CloseHandle(hOutputRead)) return 1;; if (!CloseHandle(hInputWrite)) return 1;; } void createChildProcess(char *commandLine, HANDLE hChildStdOut, HANDLE hChildStdIn, HANDLE hChildStdErr){ PROCESS_INFORMATION pi; STARTUPINFO si; ZeroMemory(&si,sizeof(STARTUPINFO)); si.cb = sizeof(STARTUPINFO); si.dwFlags = STARTF_USESTDHANDLES; si.hStdOutput = hChildStdOut; si.hStdInput = hChildStdIn; si.hStdError = hChildStdErr; if (!CreateProcess(NULL,commandLine,NULL,NULL,TRUE, NULL,NULL,NULL,&si,&pi)) hChildProcess = pi.hProcess; if (!CloseHandle(pi.hThread)) return 1;; } void readFromPipe(HANDLE hPipeRead) { CHAR lpBuffer[256]; DWORD nBytesRead; DWORD nCharsWritten; while(TRUE) { if (!ReadFile(hPipeRead,lpBuffer,sizeof(lpBuffer), &nBytesRead,NULL) || !nBytesRead) { if (GetLastError() == ERROR_BROKEN_PIPE) break; // pipe done - normal exit path. else return 1; // Something bad happened. } if (!WriteConsole(GetStdHandle(STD_OUTPUT_HANDLE),lpBuffer, nBytesRead,&nCharsWritten,NULL)) return 1;; } } DWORD WINAPI writeToPipe(LPVOID lpvThreadParam) { CHAR read_buff[256]; DWORD nBytesRead,nBytesWrote; HANDLE hPipeWrite = (HANDLE)lpvThreadParam; while (bRunThread){ nBytesRead = 21; strncpy(read_buff, "hello from the paren\n",21); read_buff[nBytesRead] = '\0'; if (!WriteFile(hPipeWrite,read_buff,nBytesRead,&nBytesWrote,NULL)){ if (GetLastError() == ERROR_NO_DATA) break; //Pipe was closed (normal exit path). else return 1;; } } return 1; } 

相当一部分上面的代码是“硬编码”，仅用于testing目的…本质上，我传递一些文本，如“你好从paren”发送到“child.exe”….

这是child.c的代码…发送给它的简单的ECHO

 #include<windows.h> #include<stdio.h> #include<string.h> void main (){ CHAR szInput[1024]; ZeroMemory(szInput,1024); gets(szInput); puts(szInput); fflush(NULL); } 

运行应用程序我发送“CallSubProcess.exe Child.exe”，它工作100％

接下来我想把“child.c”改成PYTHON SCRIPT …

 import sys if __name__ == "__main__": inStream = sys.stdin.read() outStream = inStream sys.stdout.write(outStream) sys.stdout.flush() 

那么如何改变CreateProcess调用来执行这个脚本呢？

 if (!CreateProcess("C:\\Python26\\python.exe", "echo.py",NULL, NULL,FALSE, 0,NULL,NULL,&si,&pi)){ 

但它从来没有工作。

任何想法，我可以得到这个工作？ 任何帮助将不胜感激。
