I'm working on a project that has a bitmap of permissions and I need to
find out if a user has access.=20

=20

Given permissions bit mask of 0001C0200F02000000000 where each bit
represents a specific permission

=20

And a request for permissions check on bits [37, 12, 48]

=20

What's the best way to find out if user has access to all requested
permissions?
