Question

i have a list struct:

typedef struct FaceNode{
    FaceNode *next;
    Face *aFace;
    FaceNode *prev; 
} FaceNode;

I use this struct as a member:

FaceNode *myFaces;

and initialize it like this (in a constructor)

this->myFaces = (FaceNode*)malloc(sizeof(FaceNode)*1);

Later I want to free it as follows:

FaceNode *theCurrentFaceNode;
Face* theCurrentFace;

while(this->myFaces->next){

   theCurrentFaceNode = this->myFaces;
   theCurrentFace = theCurrentFaceNode->aFace;

   this->myFaces = this->myFaces->next;

   free(theCurrentFace);
   free(theCurrentFaceNode);
}

Now my IDE tells me: “Error, too many arguments in function call” for the free call.

What is wrong about that?

Cheers

Answer 1

You have evidently declared a function of your own named free, and the compiler is finding that instead of the one you thought you were calling. Use the scope-resolution operator to call the global function:

::free(theCurrentFace);

Or find the other free function and give it a different name. It might be a member of the class you’re implementing; look in the class’s ancestor classes, too.
