Can you remove elements from a std::list while iterating through it?

Question

I\'ve got code that looks like this:

for (std::list::iterator i=items.begin();i!=items.end();i++)
{
    bool isActive = (*i)->update();
    /

I think you have a bug there, I code this way:

for (std::list::iterator itAudioChannel = audioChannels.begin();
             itAudioChannel != audioChannels.end(); )
{
    CAudioChannel *audioChannel = *itAudioChannel;
    std::list::iterator itCurrentAudioChannel = itAudioChannel;
    itAudioChannel++;

    if (audioChannel->destroyMe)
    {
        audioChannels.erase(itCurrentAudioChannel);
        delete audioChannel;
        continue;
    }
    audioChannel->Mix(outBuffer, numSamples);
}
