Detailed Description

Class to help with load of shared library functions.

You can add them as parent to your class and to help with load of shared library functions.

Note

To use on Windows must you also include p8-platform on your addon!

Example:

#include <kodi/tools/DllHelper.h>

...
class CMyInstance : public kodi::addon::CInstanceAudioDecoder,
                    private CDllHelper
{
public:
  CMyInstance(KODI_HANDLE instance);
  bool Start();

  ...

  /* The pointers for on shared library exported functions */
  int (*Init)();
  void (*Cleanup)();
  int (*GetLength)();
};

CMyInstance::CMyInstance(KODI_HANDLE instance)
  : CInstanceAudioDecoder(instance)
{
}

bool CMyInstance::Start()
{
  std::string lib = kodi::GetAddonPath("myLib.so");
  if (!LoadDll(lib)) return false;
  if (!REGISTER_DLL_SYMBOL(Init)) return false;
  if (!REGISTER_DLL_SYMBOL(Cleanup)) return false;
  if (!REGISTER_DLL_SYMBOL(GetLength)) return false;

  Init();
  return true;
}
