cpp/filesystem/path/is absrel

Checks whether the path is absolute or relative. An absolute path is a path that unambiguously identifies the location of a file without reference to an additional starting location. The first version returns if the path, in native format, is absolute,  otherwise; the second version the other way round.

Parameters
(none)

Return value
@1@ if the path is absolute,  otherwise.

@2@ if the path is absolute,  otherwise.
