C Linux Pro

This tutorial is designed to help the programmer to learn learn the debugging techniques in the c programming language. This tutorial assumes that you already know how to compile and execute programs.

What is debugging

Debugging is a methodical process of finding and reducing the number of bugs or defects in a C program.

What is a debugger

A debugger is a computer program that is used to test and debug other programs.

Debugging techniques

There are various ways to watch a running user-space programs. you can run a debugger on it and step through the program, add print statements, or add a tool to analyze the program. here we describe some methods use to debug programs that run on Linux

• Debugging by Printing
• Including Debugging Macros
• Debugging using User-space tools
• Debugging using kernel tools

There are various ways to track down user-space and kernel bugs using debug tools on Linux.

User-space tools

• Debugging with MEMWATCH
• Debugging with YAMD
• Debugging with strace
• Debugging with gdb

kernel tools

• Kernel source level debugger (kgdb)
• Built-in kernel debugger (kdb)
