Function svn_io_create_unique_link 

pub unsafe extern "C" fn svn_io_create_unique_link(
    unique_name_p: *mut *const c_char,
    path: *const c_char,
    dest: *const c_char,
    suffix: *const c_char,
    pool: *mut apr_pool_t,
) -> *mut svn_error_t

Like svn_io_open_unique_file(), except that instead of creating a file, a symlink is generated that references the path @a dest.
