Excerpt:
"
o Exception handling
The libunwind API makes it trivial to implement the stack-manipulation aspects of exception handling.
o Debuggers
The libunwind API makes it trivial for debuggers to generate the call-chain (backtrace) of the threads in a running program.
o Introspection
It is often useful for a running thread to determine its call-chain. For example, this is useful to display error messages (to show how the error came about) and for performance monitoring/analysis."
