gdb on automatic pilot?

gdb on automatic pilot?

[Aurelian Melinte]

Hello,

I am looking to use gdb to print the stack each time a certain function 
is called , then resume execution. And this without manual intervention.

Could anyone please advise if feasible and if yes, how?  Any other tool 
I can use?

Thanks,
a.

(gdb) break malloc
Breakpoint 1 at 0x483940
(gdb) commands 
Type commands for breakpoint(s) 1, one per line.
End with a line saying just "end".

(gdb) set pagination off 
(gdb) run

Sorry, I'm not sure I understood your question.  Will you be already
runnning GDB?  If so, you can put a breakpoint at the function and use
`commands' to specify what you want to do when the breakpoint is hit.
Something like:

(gdb) break f
(gdb) commands
> bt
> cont
> end
(gdb) run

Is that what you want?
