Programming

i need to know how one can get the backtrace of a program in c++
as you find in gdb or dbx on doing a ctrl c (or any signal to the os)

do help

you can use gdb's bt command when you debug the program.
or and extra code in the place of you function entry to record the function call trace.

I want to write a code which prints the backtrace as gdb's bt command prints
& not use gdb to get the backtrace
can you give me compile time options which is should need to provide to get the back trace which the binary itself prints when the user does a cntrl + c

i want to use this code in an binary which when it gets a SIGINT OR SIGQUIT should print the backtrace itself & not use gdb to get the backtrace

the information which it needs t print is line number ,cpp file & the function name

g++ -g i already know but thats for gdb

please help

It's FAR more complex than you might think because you have to trace stack frames in memory, which is hardware and OS platform-specific.

You need to download the source for your platform for gdb, and spend some time reading over the code.

Can you give me links to such sites where in i can learn about such programming

BTW i knows its difficult & thats why i want to learn it

Thanks anywayz

Use google to search for the source code of GDB.

Here is the first link that came up when gdb source code was given... Current GDB

Just be sure the code you download is for your system and OS.
