413 429 * be possible if it required multiple statements (to declare the function
414 430 * and then call it).
415 431 *
416 432 * SET_ERROR() uses the comma operator so that it can be used without much
417 433 * additional code. For example, "return (EINVAL);" becomes
418 434 * "return (SET_ERROR(EINVAL));". Note that the argument will be evaluated
419 435 * twice, so it should not have side effects (e.g. something like:
420 436 * "return (SET_ERROR(log_error(EINVAL, info)));" would log the error twice).
