Incompatible Pointer

[jumbojetjames]

hallo, in a controller-project (not CVI) I use a self-written pointerList. This list-structure has some function-pointers e.g. "int (*compare)(void*, void*)" to do something with the objects putted into the list later. so I can put into one list structures of type ABCD, in the other list structures of type EFGH and have not to manipulate the list-definition. I have only to write the methodes and initialize the list with function-pointer to these. NOW i want to do this in CVI, but the compiler says "Incompatible functions found int (*compare) (ABCD*, ABCD*) but expected int (*compare) (void*, void*)" Is there a possibility to make the compiler eating this (an option ?) or have you another idea? best regards Simon

The arguments to you function pointer need to match the arguments to the function you are loading into it.

If you function pointer is:

int (*compare)(void*,void*)

you function prototype has to be:

int FunctionName1(void *a, void *b);

int FunctionName2(void *c, void *d);
