Function libeyelink_sys::create_path

pub unsafe extern "C" fn create_path(
    path: *mut c_char, 
    create: INT16, 
    is_dir: INT16
) -> c_int

@ingroup datafile Checks if path exists. Will create directory if 'create'. Creates directory from last name in 'path', unless ends with '' or 'is_dir' nonzero. Otherwise, last item is assumed to be filename and is dropped.

@return \c 0 if exists, \c 1 if created, \c -1 if failed.
