Self stack trace

[Ajay Pal Singh]

Hi,

Anyone know's how can I get a self-stack trace of program in C.
Program could be like

#include <stdio.h>
int main(int argc, char **argv, char **envp){
/* Do something with the args */
func_a();
func_b();
/* Print stack trace to stdout or stderr */
<--------------HOW TO ACCOMPLISH THIS??
return 0;
}

func_a() {
/* Do something */
}

func_b() {
/* Do something */
}

I don't want to use pstack or dbx or forking or whatever.
Thanx in advaance.

Here is roughly the idea:

#include <stdio.h>

/*ARGSUSED*/
main(argc, argv, envv)
int argc;
char **argv, **envv;
{
register int *bp = &argc;

for (; *bp != 0; bp--) {
printf("%d\n", bp);
}
}

This is included in the FAQ posted on comp.unix.programmer. Shows
how to use the debugger to generate the stack trace.

Huh? In your example the stack would just have 'main' where you want
to print it. Is that what you want? Or do you want the process traced?
If so, then just insert trace hooks in all of your routines.

If not, and if you want to print our the processes stack segment,
then it depends. Typically, hardware provides a general purpose
register that contains a pointer to the stack segment, ie sp.

Unfortunately, C does not support a special sp register notion,
so you have to link your code to assembly to get it.

At any rate, your post seems unclear about what it is your really
after. Please explain what your looking for. Thanks.
