I am making a program that will open other programs, but some of them require administrator rights to open. I would like my program to be able to check if a file requires admin rights, and if it does then not open it. Is there a way to do this?

You can obtain the permissions with std::filesystem::file_status::permissions() if C++17 library support is available. This is unlikely, so consider using the Boost.Filesystem equivalent
http://en.cppreference.com/w/cpp/filesystem/file_status/permissions
http://www.boost.org/doc/libs/1_64_0/libs/filesystem/doc/reference.html#file_status-observers

Less preferably, use POSIX stat(2)

Or even less preferably,
GetFileSecurity() if you're on Windows.
