Feature request: readlink, nlink, copy_symlink, copy_directory, copy

[Beman Dawes]

Walter Landry writes,

I have recently upgraded from 1.32 to the current prerelease, and it feels like filesystem is missing a few convenience functions.

1) readlink: There is a way to create a symlink, but then no way to

query it later.

2) nlink: Similarly, we can create a hard link, but can not query

its link count.

3) copy_symlink: Note that this requires readlink in order to

function.

4) copy_directory: create_directory creates directories with the

mode S_IRWXU|S_IRWXG|S_IRWXO. That seems like a security hole waiting to happen. This would at least provide a way of inheriting access properties.

5) copy(): This would check what the first argument is and invoke

the appropriate function (copy_file, copy_symlink, copy_directory).

Except for nlink, I have already implemented all of these functions because I needed them. Is there any interest in getting these functions into the filesystem library?

All of these suggestions have been implemented and are part of Boost.Filesystem.

Thanks!
