获取当前进程的句柄时CreateFile失败

本文介绍了获取当前进程的句柄时CreateFile失败的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

char CurrentPath[MAX_PATH] = {0}; GetModuleFileName(NULL,CurrentPath,MAX_PATH); char BaseNameA[MAX_PATH] = {0}; GetBaseNameFromPath(CurrentPath,BaseNameA); if(hFile==NULL) { hFile = CreateFile(CurrentPath,GENERIC_READ,0,NULL,OPEN_EXISTING,FILE_ATTRIBUTE_NORMAL,NULL); if(hFile==INVALID_HANDLE_VALUE) MessageBox(0,"hFile Failed!",0,0); }

您好！ 上面的代码是随机失败的（有时它完美地运行，有时它会报告hFile Failed！）。我不太明白为什么它有时会失败。 也许我应该使用C库来打开当前进程的文件？ 也许有人知道更可靠的解决方案？ 我想要做的就是打开当前进程的本地文件我我在。 谢谢！

Hello! The code above is failing randomly (sometimes it works perfectly, other times it reports "hFile Failed!"). I don't quite understand why it fails at times. Perhaps I should use C-libraries for opening the current process's file? Perhaps someone knows a more reliable solution? Again all I'm trying to do is open the local file of the current process I'm in. Thank you!

推荐答案

尝试使用 FILE_SHARE_READ | FILE_SHARE_WRITE 作为第3个参数。 Try using FILE_SHARE_READ|FILE_SHARE_WRITE as the 3rd parameter.
