I am not able to link the CueInstance::trigger() function defined in fmod\_studio.hpp in my project. I am compiling with MSVC 2010 and linking to fmodstudio\_vc.lib from the latest fmod studio version (0.01.03).

```auto
1>ClientArea.obj : error LNK2001: unresolved external symbol "public: enum FMOD_RESULT __thiscall FMOD::Studio::CueInstance::trigger(void)" (?trigger@CueInstance@Studio@FMOD@@QAE?AW4FMOD_RESULT@@XZ)
```

Running dumpbin on the .lib reveals that there is no such exported function:

```auto
C:\Program Files (x86)\FMOD SoundSystem\FMOD Studio API Windows\api\studio\lib>dumpbin -headers fmodstudio_vc.lib | find /c "trigger"
0
```

Perhaps the C++ api for CueInstance hasn’t been implemented yet?

Sorry about that - there was a missing F\_API on the CueInstance::trigger() declaration. This has now been fixed for the next release (version 0.01.04).
