Trouble using opaque pointers in Objective C++
- by morgancodes
The answer to this quesion explains that opaque pointers are a good way to include C++ member variables in an Objective C++ header. I'm getting compile errors when trying to follow the example. Here's the relevant code from my header, with the corresponding compiler errors shown as comments:
struct ADSR_opaque; // error: forward declaration of 'struct ADSR_opaque'
@interface LoopyPulser : NSObject{
float _pulseRate;
UInt32 tickInterval;
UInt32 step;
InMemoryAudioFile * audioFilePlayer;
ADSR_opaque* env; // error: expected specifier-qualifier-list before 'ADSR_opaque'
Pattern * pattern;
float loopLengthRatio;
float volume;
}
Is there something simple I'm doing wrong here?
