mkdirhier

Creates the specified directory whole_path, but unlike the mkdir function from the standard C library, if any of the parent directories of the whole_path do not exists, they are created as well.

If the directory specified by whole_path already exists, this function performs no operation and simply returns true.

Parameters:

whole_path	path to the directory to create.
mode	file permissions to use for the newly created directories.

Returns:

true on success, else false.
