objcruntimeh

The file objcruntimeh is a header file for the Objective-C runtime library. This header provides declarations for the functions and data structures that constitute the Objective-C runtime API. Developers can include this file in their Objective-C projects to access and manipulate Objective-C objects, classes, and methods at runtime.

Key functionalities exposed by objcruntimeh include the ability to dynamically create and destroy objects, invoke methods on objects, inspect class definitions, and manage method dispatch. It is fundamental to how Objective-C achieves its dynamic features, such as message passing, dynamic typing, and the use of selectors.

When a program written in Objective-C is compiled, the compiler generates code that relies heavily on the runtime library. objcruntimeh acts as the interface between the application code and this underlying runtime system. By using the functions declared in this header, developers can perform operations that are not possible with static compilation alone, allowing for greater flexibility and expressiveness in their code. The runtime library itself is responsible for tasks like memory management, exception handling, and object introspection.
