resbuf* and acedGetVar

could someone explain me why I have error in my sample code?:


struct resbuf* Wskaznik;

int OldOsnap = acedGetVar(_T("OSMODE"), &Wskaznik); // here is error



Error 1 error C2664: 'acedGetVar' : cannot convert parameter 2 from 'resbuf **' to 'resbuf *'


I want to get system variable "OSMODE" and use it in other place in my code.

I declare OldOsnap: public: int OldOsnap;


Where I can found a good examples to use "resbuf"?

The docs for acedGetVar() very clearly state that the second argument must be a pointer to an allocated resbuf.  In your code you are passing in the address of a pointer to resbuf.  You need to change:


struct resbuf* Wskaznik;


to this:


struct resbuf Wskaznik;


and get rid of the acutRelRb() call since your resbuf is now on the stack and will be freed automatically when it goes out of scope.
