Since create_symlink(), create_hardlink(), and create_directory() exist, there's no reason not to have a create_regular_file() function.

Consider adding a function create_regular_file() with the behaviour of the POSIX touch command.

[Beman comments]

create_regular_file() and touch() should be different functions since their behavior would differ if the file already exists; touch() updates the last write date.

I have often wanted create_regular_file() but never got around to adding it.

While touch is quite useful from the command line, I'm less sure of its usefulness as a library function. It is trivial for a user to implement.

Whether or not it is appropriate to add operational functions this late in the PDTS process is questionable.
