acDbEntity like a parameter of function - problem

majklha — Sun, 13 Jul 2008 21:07:00 GMT

I tried send pointer to AcDbEntity object to my function, and AutoCad has still error - viz attached file.

this is the code:
void Pokus(AcDbEntity *textEnt)
{
}
AcDbEntity *textEnt;
Pokus(textEnt);

when I had changed type of calling parameter by reference (&), the probelm was resolved.. the new code:
void Pokus(AcDbEntity *&textEnt)
{
}
AcDbEntity *textEnt;
Pokus(textEnt);

Do somebody know, why have I to call pointer to AacDbEntity by reference ?
