<function>snd_assert()</function> macro is similar with the

normal <function>assert()</function> macro. For example,

<informalexample>

<programlisting>

<![CDATA[

snd_assert(pointer != NULL, return -EINVAL);

The first argument is the expression to evaluate, and the
|

second argument is the action if it fails. When
|

<constant>CONFIG_SND_DEBUG</constant>, is set, it will show an
|

error message such as <computeroutput>BUG? (xxx)</computeroutput>
|

together with stack trace.

When no debug flag is set, this macro is ignored.

It shows the <computeroutput>BUG?</computeroutput> message and

stack trace as well as <function>snd_BUG_ON</function> at the point.

It's useful to show that a fatal error happens there.
