[asterisk-dev] Help, can't get out of while loop

[Dennis Buteyn]

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.
