ProgrammingThis forum is for all programming questions.
The question does not have to be directly related to Linux and any language is fair game.

Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Looking the code excerpts you posted it's not clear if you are using an array of structures or a structure of arrays. The qsort header specifies the first parameter as the base pointer of the array and you are passing to it a pointer to an element of the structure and, it's not guaranteed to be the first element as it is the result of the bsearch. The second parameter must be the size of the array to be sorted and your excerpt does not give a clue from where "list_size" came. The third parameter must be the size of the array to be sorted and you give the size of a char pointer. And the last parameter may use strcmp to compare two elements of the array but, it could be used directly only if the array to be sorted is a character array.
If you could post some more code for us to see what use you do with your pointers I could help you with your sort issue.
