VC++控制台 如何得知自身程序是被哪个程序启动的

Question

C++ 如何得知自身程序是被哪个程序启动的（启动程序的路径）？
或如何设置参数，启动就能获知自身是被哪个程序启动的？
int main(int argc, const char* argv[])
{cout<< "启动我的程序是:" <<path[exe]<< endl;
}

Answer 1

被哪个程序启动的？？ 你是说哪个exe吗

Answer 2

是的， 比如c.exe b.exe 等程序（可能还有其他）都会启动 a.exe ， a.exe 如何知道是谁启动它的？

Answer 3

CreateToolhelp32Snapshot、Process32First、Process32Next
枚举进程，找到自己
然后看父进程id

Answer 4

谢谢！
就是这个思路 关键词 父进程ID

根据procesid 得到路径
HANDLE processHandle = OpenProcess(PROCESS_QUERY_INFORMATION | PROCESS_VM_READ, FALSE, parentprocessid);
char processName[MAX_PATH]={0};
GetModuleBaseName(processHandle, 0, processName, MAX_PATH) ;
char  processFullPath[MAX_PATH]={0};
GetModuleFileNameEx(processHandle, 0, processFullPath, MAX_PATH);cout<< processName<< endl;
cout<< processFullPath<< endl;

Answer 5

是的， 比如c.exe b.exe 等程序（可能还有其他）都会启动 a.exe ， a.exe 如何知道是谁启动它的？晕分数给错了别人..................
