Why doesn't the generic path grammar include syntax for portably -specifying the root directory?

-

The concept of "root directory" appears to be inherently non-portable.  -For example, "/"  means one thing on POSIX (an absolute path the single -filesystem root), and another on Windows (a relative path to the root of the -current drive).  It goes rapidly downhill from there; on the classic Mac -OS, root names can be ambiguous!

-

Why isn't there a path::is_absolute() or similar function?

-

Because useful semantics are not obvious. On some operating systems a path is clearly either absolute or -relative, but on others the distinction isn't clear. For example, on Windows consider these -paths:

Whether or not a generic path string is actually portable to a particular operating system will depend on the names used.  See the Portability Guide.

Warning for POSIX and UNIX programmers

+
POSIX and other UNIX-like file systems are single-rooted, while most other 
+file systems are multi-rooted. Multi-rooted file systems require a system-root 
+such as a drive, device, disk, volume, or share name for a path to be absolute.  
+Because of this, the root() and root_directory() functions return 
+identical results on UNIX and other single-rooted file systems, but different 
+results on multi-rooted file systems. Thus use of the wrong function will not be 
+apparent on UNIX-like systems, but will result in non-portable code which will 
+fail when used on multi-rooted systems. Thus UNIX programmers should use 
+particular care to choose between root() and root_directory().
