libunwind-dev - 1.2.1-10~deb10u1 main

The primary goal of this project is to define a portable and efficient C
programming interface (API) to determine the call-chain of a program.
The API additionally provides the means to manipulate the preserved
(callee-saved) state of each call-frame and to resume execution at any
point in the call-chain (non-local goto). The API supports both local
(same-process) and remote (across-process) operation. As such, the API
is useful in a number of applications.

This package includes the development support files.
