Multi-Paradigm Programming with Modern C++ - Application Binary Interface

The video tutorial discusses the importance of shared libraries and their relationship with the Application Binary Interface (ABI). It explains how shared libraries allow for package sharing without source code exposure and enable upgrades without rebuilding dependent applications. The tutorial covers the process of building shared libraries, maintaining ABI stability, and the challenges involved. It also explores strategies for designing interfaces, including using C style interfaces for easier ABI maintenance and combining different styles for effective interface design.

What is one of the main advantages of using shared libraries?

• They simplify the coding process.

• They increase the size of the executable file.

• They enable sharing packages without revealing source code.

• They allow for faster execution of programs.

Why is it important to maintain a stable ABI when updating shared libraries?

• To improve the performance of the library.

• To ensure the library is compatible with all operating systems.

• To reduce the size of the shared library.

• To prevent applications from crashing or needing recompilation.

What can potentially break an ABI in a shared library?

• Changing the operating system.

• Adding a new function to the library.

• Modifying a private data member in a class.

• Increasing the library's version number.

What is a benefit of using C-style interfaces in shared libraries?

• They make maintaining ABI stability easier.

• They support object-oriented programming.

• They allow for more complex data structures.

• They enable faster execution of functions.

What is the curiously recurring template pattern used for?

• To ensure compatibility with older versions of a library.

• To improve the performance of shared libraries.

• To simplify the syntax of C++ code.

• To create large class hierarchies without virtual calls.
