Function svn_path_is_canonical 

pub unsafe extern "C" fn svn_path_is_canonical(
    path: *const c_char,
    pool: *mut apr_pool_t,
) -> svn_boolean_t

Return @c TRUE iff path is canonical. Use @a pool for temporary allocations.

@since New in 1.5. @deprecated Provided for backward compatibility with the 1.6 API. New code should use svn_dirent_is_canonical(), svn_uri_is_canonical(), svn_relpath_is_canonical() or svn_fspath__is_canonical().
