NAME¶

snd_BUG_ON - debugging check macro

SYNOPSIS¶

snd_BUG_ON(cond);

ARGUMENTS¶

cond

DESCRIPTION¶

When CONFIG_SND_DEBUG is set, this macro evaluates the given condition, and call WARN and returns the value if it´s non-zero.

When CONFIG_SND_DEBUG is not set, this just returns zero, and the given condition is ignored.

NOTE¶

the argument won´t be evaluated at all when CONFIG_SND_DEBUG=n. Thus, don´t put any statement that influences on the code behavior, such as pre/post increment, to the argument of this macro. If you want to evaluate and give a warning, use standard WARN_ON.
