wdb debugger - High Level Programming

Sven28 · #1 12-03-2001

Hi all,
is it possible to skip a function with the wdb debugger ?
could be helpful instead of compiling the whole bunch again
does someone know how to do this ?

thx

Sven

As I understand it, wdb is just a front-end to gdb. If so, you can "jump" past any function easily. For example, if you are debugging the following code:

Code:

printf("hello, world\n");
this_is_my_function();
printf("goodbye, world\n");

as you are stepping through the code -- lets say you are at line 1 -- you can enter "jump 3" to jump immediately to line 3 thereby skipping line 2 and the function call entirely. If you want to automatically skip a function as the program runs (with no input needed), you might give the following commands to the debugger:

Code:

break this_is_my_function
commands
return
continue
end

That would tell gdb to stop at the specified function, and automatically execute the commands "return" and "continue" which would have the same effect as skipping the function entirely.

And how do i get the line number ? where im currently at ?

In gdb as you step through the code the line numbers are displayed. You can type "l" or "list" to see a block of code around the current line. You can type "bt" or "backtrace" to see the function stack.
