Hi, I looked yesterday in kmix code and I see this,
which I think is a bit wrong, or I do not understand why
close() is called even if open fails - we just want to know if mixer is valid.
bool Mixer_Backend::isValid() { bool valid = false; int ret = open(); if ( ret == 0
&& m_mixDevices.count() > 0)
{ valid = true; } close(); return valid; }
regards
The code makes sense to me at a very superficial sight.
open() may succeed but the "if" could fail is m_mixDevices.count() is <=0. So
calling close() even if the "if" fails
makes sense, as long as close() does nothing wrong if open() had previously failed.
Cheers
