how to stop execution in for loop

useless79 · #1 (**permalink**) 09-06-2007

Hi all,

I am working on a c source code nearly 2000 line . it contains one big for( i=0; i< 200 ; i++ ) loop of around 600 lines
could any tell me how to break the execution of prog when the value of i is 50 in for loop so that i can check
inside the loop.

Thanks..

Do you mean in a debugger?

One pretty good way is to recompile the program with the following somewhere in the loop...

Code:

if (i==50) { ((void **)0)[0]=0; }

That should give you a nice core dump.

Otherwise do similar but just have a line that you can set a break point on..

Code:

if (i==50)
{
     i;  /* set breakpoint here */
}
