Edit Question
Title
Body
We have a server (written in C and C++) that currently catches a SEGV and dumps some internal info to a file. I would like to generate a core file and write it to disk at the time we catch the SEGV, so our support reps and customers don't have to fuss with ulimit and then wait for the crash to happen again in order to get a core file. We have used the abort function in the past, but it is subject to the ulimit rules and doesn't help. We have some legacy code that reads /proc/pid/map and manually generates a core file, but it is out of date, and doesn't seem very portable (for example, I'm guessing it would not work in our 64 bit builds). What is the best way to generate and dump a core file in a Linux process?
