Defined in header <experimental/filesystem>
path canonical( const path& p, const path& base = current_path() );	(1)	(filesystem TS)
path canonical( const path& p, error_code& ec );	(2)	(filesystem TS)
path canonical( const path& p, const path& base, error_code& ec );	(3)	(filesystem TS)

Converts path p to a canonical absolute path, i.e. one that has no dot, dot-dot elements or symbolic links. p is optionally relative to base.

p must resolve to an existing file, otherwise error occurs.

The return path resolves to the same path as absolute(p, base (or absolute(p) for (2)}}.

Parameters

ec

-

error code to store error status to

Return value

The canonical absolute path of p, which is optionally relative to base.
