createprocess运行BAT文件

Question

我在DOS提示符下运行MM.BAT运行成功,生成两个有内容的DAT文件,用C语言调用Createprocess函数执行MM.BAT的时候发现生成两个空文件:

STARTUPINFO si;
PROCESS_INFORMATION pi;
si.dwFlags = STARTF_USESHOWWINDOW;
si.wShowWindow = SW_HIDE;
si.cb = sizeof(si);
ZeroMemory(&si, sizeof(si));
CreateProcess("mm.bat", NULL,NULL,NULL,FALSE,CREATE_NO_WINDOW,NULL,NULL,&si,&pi);
WaitForSingleObject(pi.hProcess, INFINITE);

Answer 1

mm.bat:

sed "s/feaf/feawc23/" C:\DLNAME1/feaw.dat>D:\car/feaw.dat
sed "s/feaf/feawc23/" C:\DLNAME1/feaw2.dat>D:\car/feaw2.dat

Answer 2

你需要用管道读取

Answer 3

int CreateProcessWithPipe(char* szCmdLine, CPWP_STRUCT* pcs)

这个函数怎么调用?

CreateProcessWithPipe("sed \"s/feaf/feawc23/\" C:\DLNAME1/feaw.dat>D:\car/feaw.dat,"&cs)
