Function svn_io_copy_link 

pub unsafe extern "C" fn svn_io_copy_link(
    src: *const c_char,
    dst: *const c_char,
    pool: *mut apr_pool_t,
) -> *mut svn_error_t

Copy symbolic link @a src to @a dst atomically. Overwrite @a dst if it exists, else create it. Both @a src and @a dst are utf8-encoded filenames. After copying, the @a dst link will point to the same thing @a src does.
