size of struct with pointers and function pointers

[sdsjohnny]

Hi,

I following structure

typedef struct
{
UINT32 abc;
int (*f)(int a, intb);
char *ptr;
} my_struct;
 
main()
{
my_struct myParams;
sizeof(myParams);
}
 

Assume int is 4 bytes and char is 1 byte. I know the size of structure without pointers inside. But I am not sure with pointers and function pointers. Is it 4+4+4(12) or something else??

Thanks in advance.
Johnny

Yes. Size is 12.

On a 32 bit system, on a 64 bit system your pointers are likely to be 8 bytes not 4.
