This project is a source code repository for instructors or expert programmers who want to explore the Linux C/C++ API.

number of examples and their selection

Currently there are 954 examples in this repo. These are the examples I found are useful in explaining the Linux API. The idea is to provide a good coverage of all major features and to resolve disputes about exactly how a certain API works.

Topics covered by the examples

• Multi-threading
• Multi-processing
• Locking
• Calling system calls without C
• Performance
• Coding in assembly
• Various compiler directives
• Many more...

Platforms supported

Only ia64 is supported. I used to support i386 but I don't have a 32 bit machine anymore. Other platforms will be supported if someone is willing to do the work and submit the patches.

Contributing

This project needs help. fork, commit and request me to pull. Just open a github account, modify and add examples, commit and ask me to pull... A lot of the code is documented but some of it is not. More documentation would be welcome. I would give attribution to whomever contributes.

License

Code is licensed GPL3 and I hold the copyright unless explicity stolen as attributed in the source code. I encourage people to use this source code as aid for instructing courses. Please give me some credit if you do wind up using this package and consider dropping me a note about the fact that you did use the package so I could feel good...

Similar projects

Michael Kerrisk, the maintainer and author of many of the Linux manual pages has a similar project he calls TLPI (The Linux Programming Interface) of programs he used in his book of the same title. You can find it here http://man7.org/tlpi/code/.

Using it

• you need python on your machine: try: python --version if python is missing then: for deb based distributions (debian, ubuntu, ...) do: sudo apt-get install python for rpm based distributions (fedora, redhat, centos,...) do: sudo yum install python
• clone the examples: git clone git@github.com:veltzer/demos-linux.git
• cd into it: cd demos-linux
• install the missing packages and headers needed to compile and run this project ./scripts/ubuntu_install.py Mind you this only works for 15.10 and will install a ton of stuff. If you don't want this ton of installations and only want to checkout specific examples compile the individual examples as described below. if you are on a different Linux distribution try to get as much of these for your platform as you can. If you really into contributing I would love a redhat_install.py or some such... then use make
• compiling a specific example make src/examples/performance/cache_misser.elf the name of the elf binary is the same as the example source code with .elf instead of .[c|cc]. You must be at the root of the project to issue the make command.
• the most important part: tweak the examples, try to prove me (my comments) wrong, have fun!
