I have a struct like this

typedef struct _somestruct {
    int a;
    int b;
}SOMESTRUCT,*LPSOMESTRUCT;

I am creating an object for the struct and trying to print it's address like this

int main()
{
    LPSOMESTRUCT val = (LPSOMESTRUCT)malloc(sizeof(SOMESTRUCT));

    printf("0%x\n", val);

    return 0;
}

..and I get this warning

warning C4313: 'printf' : '%x' in format string conflicts with argument 1 of type 'LPSOMESTRUCT'

So, I tried to cast the address to int like this

printf("0%x\n", static_cast<int>(val));

But I get this error:

error C2440: 'static_cast' : cannot convert from 'LPSOMESTRUCT' to 'int'

What am I missing here? How to avoid this warning?

Thanks.
