Getting stack frame of a thread
 

Hi All,

I am new to this forum, my first question here is,

Is it possible to get a call stack of a thread when it is running, either by using proc utilities or by some standard library calls ?
(Note: No core dump, and dont want to dump a core)

You can attach a debugger while it's running.
Or "gcore" while the program runs and "gdb prog core" with "thread apply all bt".

Thanks for the reply, but my requirement is little different, i wanted to run a program which periodically takes the call stack of the specified thread ?

do you still think with "gcore" it is possible ?

Do you know any other way ?
