What is Jenkins pipeline library?
Jenkins Shared library is the concept of having a common pipeline code in the version control system that can be used by any number of pipelines just by referencing it. In fact, multiple teams can use the same library for their pipelines. You can compare it with the common programming Library.

Simply put, A shared library/ Dynamic Library is a library that is loaded dynamically at runtime for each application that requires it. They load only a single copy of the library file in memory when you run a program, so a lot of memory is saved when you start running multiple programs using that library.

What does it mean to use shared library in Java?
These libraries are considered “trusted:” they can run any methods in Java, Groovy, Jenkins internal APIs, Jenkins plugins, or third-party libraries. This allows you to define libraries which encapsulate individually unsafe APIs in a higher-level wrapper safe for use from any Pipeline.
Create a file library.c with the following content. The file library.c defines a function signum which will be used by our application code. Compile the file library.c file using the following command. The flag -shared instructs the compiler that we are building a shared library.
How to link an application to a shared library?
When we link an application against a shared library, the linker leaves some stubs (unresolved symbols) to be filled at application loading time. These stubs need to be filled by a tool called, dynamic linker at run time or at application loading time. Again loading of a library is of two types, static loading and dynamic loading.
