SND_BUG_ON(9) Miscellaneous Functions SND_BUG_ON(9)NAMEsnd_BUG_ON - debugging check macro
SYNOPSISsnd_BUG_ON(cond);
ARGUMENTS
cond
condition to evaluate
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.
