Previously some structures in the C language how to represent?

            


struct b
{
int b0;
int c0;
......
};

struct a
{
struct b * b1;
int b2;
..
};

struct c
{
struct a * a1;
int a2;
....
};

For the above c language definition, symbian how mean? They are represented as a class C it? Or T class? How to deal with the situation of insufficient memory allocation?
These are not very clear! Please have had the experience of people talk about, I now some of the windows on the c program ported to symbian, in some places not allowed to grasp. Thank you!

What is the structure used to be ported to symbian on what to use, you do not have to turn into a class

Anyway support structure

But if it can not allocate enough memory, how to handle it? The system will not be an exception to launch?
Reply:
Yes ah, I also think since support, why should we spend so much of its class
Reply:
T class turn to try.
