How to access initialized values of global variables

[Swati Rathi]

I am trying to fetch the initialized values of global variables.
For eg : int i = 10;

I am able to extract the value using DECL_INITIAL.
But when I have a case like below,

struct node
{
int x;
int y;
};

struct node n1=
{
99,
88,
};

I get value as {.x=99, .y=88}

How should I iterate to fetch 99 and 88 individually?
In a way I want to access individual variables initialized values.
Can someone tell me the way to do it.

[pjb@kuiper :0 tmp]$ cat a.c
#include <stdio.h>

struct node
{
int x;
int y;
};
struct node n1=
{
99,
88,
};

void iterate(){
int* refs[]={&n1.x,&n1.y,0};
int i;
for(i=0;refs[i];i++){
printf("%d: %d\n",i,*(refs[i]));
}
}

int main(){
iterate();
fflush(stdout);
return(0);
}
[pjb@kuiper :0 tmp]$ gcc -o a a.c
[pjb@kuiper :0 tmp]$ ./a
0: 99
1: 88
[pjb@kuiper :0 tmp]$
