Hi, all! I'd like to know some details about segmentation fault. What I mean is when a program accesses invalid memory area, it will get a SIGSEGV signal from kernel, and a message "Segmentation fault". I also find that dmesg can show we some details like this: ProgramName[Pid]: segfault at xxxx eip xxxx esp xxxx error x It is useful and provides the first-step information for further debug/analysis. My question is how dmesg gets the information, and if there are any programmable interfaces we can call to get this. (e.g. we can write sig handler for a program to print this message and maybe do some auto analysis) Thank you. Leo
