OpenVR GetStringTrackedDeviceProperty Wrapper

example.cpp

std::string GetStringTrackedDeviceProperty( vr::IVRSystem * pSystem, vr::TrackedDeviceIndex_t unDeviceIndex, vr::ETrackedDeviceProperty prop, vr::ETrackedPropertyError *pError )
{
	vr::ETrackedPropertyError err = TrackedProp_Success;
	std::string sRetVal;

	char buf[32];
	uint32_t unPropLen = pSystem->GetStringTrackedDeviceProperty( unDeviceIndex, prop, buf, sizeof( buf ), &err );
	if ( err == vr::TrackedProp_Success )
	{
		sRetVal = buf;
	}
	else if ( err == vr::TrackedProp_BufferTooSmall )
	{
		char *pchBuffer = new char[unPropLen];
		unPropLen = pSystem->GetStringTrackedDeviceProperty( unDeviceIndex, prop, pchBuffer, unPropLen, &err );
		if ( err == vr::TrackedProp_Success )
		{
			sRetVal = pchBuffer;
		}
		delete[] pchBuffer;
	}

	if ( pError )
	{
		*pError = err;
	}
	return sRetVal;
}

Nice wrapper, I was about to write one similar!
