Generate minimal and customized core dump files on Linux.
The minicoredumper project provides a program that handles the creation of core dump files on Linux. It can produce much smaller core dump files by making use of sparse files, compression, and allowing the user to configure what parts of the process memory image should be dumped.
By using libminicoredumper, an application can register exactly what data should be dumped by minicoredumper. This data will not only be dumped in case of a crash, but also can be triggered to dump during runtime.
The minicoredumper project provides a tool to trigger libminicoredumper-based applications to dump their registered data while running. If any of the applications should crash, minicoredumper will trigger the others to dump their data as well.
