bool Frame::setAU (  AU *  au,
bool  detectType = true
) 
 

fills the buffer with an AU.

au != NULL must be true. Problem: calling resize on the buffer, is not advised.Definition at line 87 of file Frame.cpp.

bool Frame::unsetAU (   ) 
 

removes the previously set AU, so it will not be freed in Frame destructor.

You must delete the AU outside the class, otherwise you'll have a massive memory leak!Definition at line 109 of file Frame.cpp.
