求问关于GetCurrentProcess()函数问题?

Question

1：GetCurrentProcess 获取当前进程的一个伪句柄 ，它和进程句柄之间有什么关系？？这个伪句柄 是当前的程序还是别的？？2：OpenProcessToken这个函数的第一个参数，如果不是用GetCurrentProcess获取的伪句柄可以不？？

Answer 1

The return value is a pseudo handle to the current process.
A pseudo handle is a special constant that is interpreted as the current process handle. The calling process can use this handle to specify its own process whenever a process handle is required. Pseudo handles are not inherited by child processes.
　　BOOL OpenProcessToken(
　　__in HANDLE ProcessHandle, //要修改访问权限的进程句柄
　　__in DWORD DesiredAccess, //指定你要进行的操作类型
　　__out PHANDLE TokenHandle //返回的访问令牌指针
　　)；
