Welcome to Part 2 of this series, in which we will look at C language’s concept of pointers and structs.

Later on in this article, we will use Panama to mimic these concepts.

The goal is to call C function signatures that are often defined to accept pointers and structs.

In this series of articles, we will explore the APIs from OpenJDK’s Project Panama.

My intent is to show you how to be proficient in using the Foreign Linker APIs (module ‘jdk.incubator.foreign’) as it relates to Java interoperability with native code.

While this article is for newbies, I assume you know the basics of the Java language, a little bash scripting, and a familiarity with C programming concepts. If you are new to C language don’t worry I will go over the concepts later.
