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.

DL(3)							     Library Functions Manual							     DL(3)

NAME

       DL - generate logging messages in C and C++ using a debugger

SYNOPSIS

       #include <DL.h>

       DL(format,...)

       DLG(guard,format,...)

       DLH(handler,format,...)

       DLP(param,format,...)

       DLGH(guard,handler,format,...)

       DLHP(handler,param,format,...)

       DLGHP(guard,handler,param,format,...)

DESCRIPTION

       The  DL	macro  is  used  to print logging or debugging messages using a debugger. The nana(1) command generates a set of debugger commands
       which are then sourced into gdb(1) to implement the logging. If you don't run the executable under gdb(1) then no tracing will occur.   The
       arguments are:

       format,... - a printf(3) style argument list containing the message

       guard - print only if the guard is true.

       handler - the code that does the printing. Default: fprintf

       param - a parameter to be passed off to the handler. Default: stdout

       See nana.info for details on configuring the behaviour.

       nana-clg(1), nana(1), nana(3), I(3), DI(3), L(3), DL(3), Q(3) and nana.info.

       The nana.info file is the primary documentation for this library.
