问题
I am writing a Cross platform application using C++/STL/Boost and I realized they do not provide a way to check if a folder or file is hidden or is a system file in Windows.
What's the simplest way to do this in C/C++ for Windows ?
Ideally I have a std::string with the path (either to a file or folder), and would return if it's hidden or is a system file. best if it works across all windows versions. I am using MinGW g++ to compile this as well.
回答1:
GetFileAttributes will work for this.
It takes a path to either a file or a directory as a parameter and returns set of flags including FILE_ATTRIBUTE_HIDDEN and FILE_ATTRIBUTE_SYSTEM.
DWORD attributes = GetFileAttributes(path);
if (attributes & FILE_ATTRIBUTE_HIDDEN) ...
if (attributes & FILE_ATTRIBUTE_SYSTEM) ...
