len: The number of attribute elements to retrive.
ind: The indices of the desired attribute elements.
values: A pointer to the location where the requested attribute elements should be returned. Note that the result array must be as long as the requested index list.
Example usage:
int desired[] = {0, 2, 4, 6};
char vtypes[4];
error = GRBgetcharattrlist(model, "VType", 4, desired, vtypes);
