Comments on: Crash Handling https:/code-sample/crash-handling/ Developer resources for the X-Plane flight simulator Wed, 27 Apr 2022 20:22:48 +0000 hourly 1 https://wordpress.org/?v=6.6.1 By: Tomasz https:/code-sample/crash-handling/#comment-41273 Wed, 27 Apr 2022 20:22:48 +0000 http://developer.x-plane.com/?post_type=code-sample&p=39932#comment-41273 This example doen’t compile on Linux. It uses C99 feature “designated initializers” that is not avaliable in CPP.

It can also show the backtrace and some other stuff: https://github.com/ssbssa/gdb/releases

It is not a suggestion that you add crash handling; it provides examples and guidelines so that if you _do_ provide crash handling, you do so in a way that doesn’t interfere with everyone else’s crash handling.

It is not meant to be illustrative of signal handling in general – your plugin should not be using posix signals, except as shown here to catch seg faults.
