struct and members addresses

[Cédric Lucantis]

Hello

   I would like to know if I can assume that a structure and its first member
will always have the same address. For instance, with the following code:

/* ----------------------------------*/

struct foo
{
   any_type    first_member;
};

struct foo my_struct;

void * addr1 = &my_struct;
void * addr2 = &my_struct.first_member;

/* ----------------------------------*/

can I be sure that `addr1' will be equal to `addr2' ?

thanks
