how to get gdb to step thru called functions


Trying to use gdb to check on code, but when I use -tui and reach a function call, I am unable to evaluate what happens in the called function-----it simply stays in main with the returned value.
Anyone who understands my problem and can provide what I need to do to correct this?

NevemTeve;
Yes, that was very helpful. Unfortunately, it didn't help me with my code problem, but that's for tomorrow to try to figure what's wrong.
I've always tried to avoid the 's'tep command, as the code shown is way over my head. But that combination will be very helpful to me in the future.

I think you want to be prudent about where you step over functions, and where you step into functions. Stepping into library functions like Standard C Lib functions or third party API functions is usually not helpful. Stepping into the functions you create for your own project is more likely to be useful.

yes, that's exactly what I was experiencing. Now that I see how to step 'into' a function, it becomes so much more clear.
