[Connect C++ Migration]mdlClip_... Parameter

Question

Hello together, 
 My colleague has the following problem: 
 void foo(void)
{
 ClipVectorPtr clipP = NULL;
 if (mdlClip_fromElement(clipP, elDescr, false, view) == SUCCESS)
 {
 if (mdlClip_isElemInside(&bOver, edP, clipP, view, true)){&hellip;}
 }
 mdlClip_free(&clipP);
}
 
 "mdlClip_fromElement" fills "ClipVectorPtr". But "mdlClip_isElemInside" needs "ClipVectorCP". Must there be some converting or only some typecasting? 
 And he miss "mdlClip_free", also it is referenced several times in the help-file. 
 Thank you very much!

ClipVectorPtr is a ref-counted pointer that holds a ClipVector, it will free itself when it goes out of scope/is no longer referenced. Code should be updated as follows: 
 void foo(void) { ClipVectorPtr clip; if (mdlClip_fromElement(clip, elDescr, false, view) == SUCCESS) { if (mdlClip_isElemInside(&bOver, edP, clip.get(), view, true)){&hellip;} } }
