Compiler Error C2227

left of '->member' must point to class/struct/union/generic type

The operand to the left of -> is not a pointer to a class, structure, or union.

The following sample generates C2227:

// C2227.cpp
int *pInt;
struct S {
    int member;
} s, *pS = &s;

int main() {
   pInt->member = 0;   // C2227 pInt points to an int
   pS->member = 0;   // OK
