I'm trying to write code that will identify the space available in a given directory on a system with several mount points an a plethora of hard links. This is simple, and works:

@result = `df -Pk $directory`;

I would be more comfortable with a solution that would not create an external system call. I know that I can get the device ID for the mount point on which $directory is stored with a stat() call, but I haven't found a way to use $dev to find more infomation about the device.

I feel that there should be a simple way to do this, but I can't find it.
