generic gdb macro for tree walk.

[sinbad]

Hi,

Is it possible to write generic gdb macro for a tree walk. for instance i have two types of trees as follows.
Does gdb macro provide for c_macro style replacement so that i can specifiy what is the left pointer and right
pointer and the data variable for the tree.

typedef struct tree_one_data {
int x;
}tree_one_data_t;

typedef struct tree_one {
void *left;
void *right
tree_one_data_t *data;
};

typedef struct tree_one_data {
char x;
}tree_two_data_t;

typedef struct tree_two {
void *lpointer;
void *rpointer;
tree_two_data_t *data;
};

thanks

Do your own coursework. Plus that is a generic C question, not a unix one.

I think you misunderstood me. it's not a C question, it's a gdb macro question and i think this is the right forum to ask.

I did in fact check gdb scripting manual, couldn't find anything obvious.

I tend to agree. However, I'm unsure if people on c.u.p. generally
know a lot about customizing gdb. I don't, sorry.

Then you have an excuse to ask on a gdb mailing list, if there is one.

I think you've misunderstood what gdb macros are. They are limited to
making C source more comprehensible when using gdb. (That is, unless
*I've* misunderstood since I'm not much of a gdb user!)

So, in short, no.
