C Project template

Aim of this Repository is to create a template repository for C executable projects with following properties:

• Cmake project
• Logging support

These requirements will keep updating.

Cmake Project

• Cmake is the build automation system system used with this project.
• Cmake can also be used to run tests.

How to build

• Source of this repository is the git root folder.

• Go to source of repository.

• Create a folder build

• Go to build and use cmake.

$ mkdir build
$ cd build
/build$ cmake ..

• Cmake has not build the project yet. It will create the Makefile.
• Run Make to create the executable.

$make

• The output executable will be in the {source folder}/bin. This has been configured in Cmake. You can edit this.

Logging support

• I have used log.c as the logging library.
• It is added in the {source folder}/ext folder.
• All external libraries used will be added here.

How is it used

• I am using logging library to create a file and writing logs to it.
• File will be created in {source folder}/logs . If the folder doesn't exits, it will create the folder.
• filename will be the timestamp when file is created.
• I am initialising logging in logging.c, a call to init_log().
  • NOTE: I have created a init_utils() that will tackle all initialisation for utils.

The demo

• I have created the demo where I am doing a dns lookup and managing the heap memory.
• I have created a my_malloc function which calls malloc and stores the allocated pointer in a linked list.
• I am freeing the memory in the function FREE_HEAP() that frees all elements of this linked list.
• I am then using atexit call when starting app to call FREE_HEAP whenever the app exits.
