Using the libraries in src platforms


I am looking at the platforms library and I was hoping if someone could help me understand the functions contained in the different libraries I can use to write simple apps for my PX4.


px4_log.h - This library gives me access to the LOG, WARN, ERR and PANIC functions under the default build. I was hoping to get a better explanation as to what they actually do. What is the difference in output?

Thanks in advance.
