Install: brew install libunwind-headers

About:
Libunwind-headers provides the C header files and documentation for the libunwind library, which defines a portable and efficient C programming interface (API) for determining the call-chain of a program. This API allows for the exploration and manipulation of a program's stack frames, enabling tasks like stack walking and exception handling. It is a foundational component for low-level system diagnostics and debugging tools on Apple platforms.

Key Features:

Defines a standard C API for stack unwinding
Supports both local (in-process) and remote (cross-process) unwinding
Provides mechanisms for finding and manipulating stack frame information
Essential for implementing exception handling and debuggers

Use Cases:

Implementing robust exception handling mechanisms in C++ or Objective-C
Building debuggers, profilers, and crash reporting tools
Performing stack traces for diagnostic logging

Alternatives:

libexecinfo – A simpler BSD-licensed library for backtrace generation, primarily found on non-Apple systems.
Boost.Stacktrace – A C++ library that provides stack trace functionality, often used for cross-platform applications.
