373 | * snd_BUG_ON - debugging check macro | |
374 | * @cond: condition to evaluate | |
375 | * | |
376 | * When CONFIG_SND_DEBUG is set, this macro evaluates the given condition, | |
377 | * and call WARN() and returns the value if it's non-zero. | |
378 | * | |
379 | * When CONFIG_SND_DEBUG is not set, this just returns zero, and the given | |

381 | * | |
382 | * NOTE: the argument won't be evaluated at all when CONFIG_SND_DEBUG=n. | |
383 | * Thus, don't put any statement that influences on the code behavior, | |
384 | * such as pre/post increment, to the argument of this macro. | |
385 | * If you want to evaluate and give a warning, use standard WARN_ON(). | |
