      Parameters

      path

      const(char)* base

      Split path (such as that returned by getenv("PATH")) into pieces, each piece is mem.xmalloc'd Handle double quotes and ~. Pass the pieces to sink()

      Parameters

      Declaration

      static nothrow bool ensurePathExists(const(char)[] path);
      static nothrow bool ensurePathExists(const(char)* path);

      Ensure that the provided path exists

      Discussion

      Accepts a path to either a file or a directory. In the former case, the basepath (path to the containing directory) will be checked for existence, and created if it does not exists. In the later case, the directory pointed to will be checked for existence and created if needed.

      Parameters

      const(char)[] path

      a path to a file or a directory

      Return Value

      true if the directory exists or was successfully created

      Return canonical version of name. This code is high risk.
