How can I debug a function in particular file of a running application using gdb?

Question

I have made an application in which there is a file main.c which uses a function from the master.c file. I would like to debug my application for all functions defined in the master.c file by using gdb tool . Is this possible and if so how?

Answer 1

You must compile your program using -g flag.

Then you start gdb your_program and set break points: break master.c:37 that will set a break point on master.c, line #37 or you could set breaks at functions: break foo() .

Then start your program by run and continue with the debugging process, inspect , continue , watch , display ...
