Hi,

I have two structs say:

Code:
struct a
{
int xyz;
char aStringArray[20][80];
};

struct b
{
bool b;
char ** aStringArray2;
};
Then I have a function that receives first struct as input and calls another function passing the second struct.

Code:
void exampleFunc1(struct a * mem_a)
{
struct b mem_b; 
if (mem_a->xyz) mem_b.b = true;
else mem_b.b = false;

/* update mem_b.aStringArray2 using the info from mem_a*/

/* should I allocate the memory or I can use the memory already allocated for mem_a ? */

/* I know that mem_a will survive longer than mem_b */

/* call second function passing mem_b */

exampleFunc2(&mem_b);

/* if I allocated memory explicitly then destroy it now as we no longer need it */

/* mem_a memory is not headache of this function so let's return */
return;
}
Thanks for any ideas
