memory allocation and freeing

Greetings,

Okay, heres two structures
:

Code:

---


struct TEST
{
    char  *var1;
    DATA  *data;
};

struct DATA
{
    char  *datavar;
};

---

lets say I allocate the memory and everything. When I get to the point that I need to free() it I have a questions.

lets say we have...

struct TEST test1;

if I free(test1); does it free *var1, and *data too? or do I need to seperately free them as well? also, if I were to... test1=NULL; will it NULL var1 and data too? or, again, do I need to do those seperatley?

Thanks, any help on these minor questions will be most appreciated, as well as any other insights.

If you allocate memory for any members explicitly, you need to free it, along with the struct itself.
