Question

I have the following code:

typedef struct{
int A; 
char* B;
}MYTYPE;

MYTYPE sample;
int nCount; 

void doSomething(int A, MYTYPE* B)
{
//doing something inside this function.
}

doSomething(nCount, &sample);

Is there a way in my function doSomething() to check if the second argument passsed was exactly sample?

Answer 1

Yes:

if(B == &sample)
{
  printf("Get your own, don't use sample!\n");
}

note that your call is wrong, you need:

doSomething(nCount, &sample);
                    ^
                    |
               IMPORTANT!

Since the function expects an address. It will not build, as written in the question.
