Thread: 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.
