How to access **pointer from structure

[eeshani]

Hi,

I want to access ** pointer from pointer to structure. Pls guide me in the code given below:

sturct m
{
int i;
struct n ** pCurrLine; // Ram pointer
struct m *prev;
struct m *nxt;

};

struct n
{
int x[10];
struct n *pre;
struct n *nxt;
};


*pcurrline = &pLine_cur_p tr;
struct n *pLine_cur_ptr;
pLine_cur_ptr = &cur_Line;

struct m *mCurr;

Now if I have to access pCurrLine then how should I proceed.

I tried :

mCurr->pCurrLine = mCurr->pCurrLine->pre ; // error

mCurr = mCurr->pre; /// Is right


pls help

Thanks,

*pcurrline = &pLine_cur_p tr;

if pcurrline is not initialized ( points nowhere ) you will write
this pointer somewhere in ram. It is not good.

I tried :

mCurr->pCurrLine = mCurr->pCurrLine->pre ; // error

mCurr->pCurrLine is a pointer to pointer, so you need something like
(*(mCurr->pCurrLine))->pre

Thank you...I worked according to your suggestion. I am also type casting the ROm pointer into RAM so its working at this stage...lets see
Once again Thanks...I appreciate your help.
