While we consider Stas' ideas for a portable tmpdir, we should also consider
breaking apart path strings (such as env('PATH'), or LIB or INCLUDE paths
as well.) These semantics change considerably from Win32 to unix and
other platforms. I dunno what NetWare does here, anymore.
If you need the implementation details look at how Perl does it. it's in File::Spec which is a set of function working on Files/Dirs crossplatform. In this particular case these are the functions you want to look at:
splitpath
splitdir
catdir
catfile
and a few other useful functions.Currently Perl includes implementations for:
