That loop is equivalent to:
audiohook->status = AST_AUDIOHOOK_STATUS_SHUTDOWN;
while (audiohook->status != AST_AUDIOHOOK_STATUS_DONE) {
sleep(...);
}
Something else (in another thread) must change the status in order for
that loop to terminate.
Side note: that struct member probably should be marked volatile, I can
imagine very eager compilers assuming that status never changes and
optimizing that code into a real infinite loop.

Hello ,
I'm developing a module on asterisk, while debugging i've come across
a problem I don't quite understand.
I'm using a noise filter, at the end of the call I stop my filter , so
clean up everything, detach the audiohook and there is the problem.
It's stuck in the while loop in *ast_audiohook_detach*.
As far as I understand, to detach audiohook, the status should not be
*NEW* nor *DONE*, then it's update its status to *SHUTDOWN* which will
then put it to *DONE*, so why does it get stuck in the while loop and
don't update it's status to *DONE* ?
Thank you in advance for your help.
