Curl: Help us out in the curl project

We brought some older UNIX systems to the Internyet part and made it our happy place!

In the #curl project, being written in C, we always work on simplifying the code. One way is to use more internal helper functions and avoid direct use of some functions that are often involved in C mistakes/vulnerabilities.

To measure how this develops, we count number of these function calls used per every thousand lines of code. Over time.
In a graph.

At last!

When shown the huge list of operating systems curl runs on, people often ask me which is the strangest, or hardest, operating system to keep curl support for. The answer is always, and will probably always remain: Windows.

No other operating system has so many custom, special, weird and quirky ways that require special-case solutions in the code.
