Struct storage with char* type ?

Here's the problem, ...

/*===================*/
Struct identifier
{
char* name;
int value;
}

struct identifier id[100];

/*===================*/

So, basically I have an array of structures.....

Lets say I have....

/*====================*/
char **tokenbuffer;

id[0].name = tokenbuffer[0];
id[1].name = tokenbuffer[1];

etc....

Then,... I eventually NULL out all the cells of tokenbuffer in a for loop.

The problem is that once I do this, I wipe out the id[].name
values in my struct as well. I suppose this is because I'm really
storing a pointer in id[].name because it is of type char*. How
can I resolve this problem, i.e. keep the struct from changing
when I alter tokenbuffer ?

-jay

Use malloc

id[0].name = malloc( strlen(tokenbuffer[0]) + 1 );
strcpy( id[0].name, tokenbuffer[0] );

The problem is, you're making the structure point to the 'tokenbuffer'. Naturally, when you make changes to the 'tokenbuffer', you affect whatever is pointing at it.
