Recommendation ________________________________________________________________________
You can create a dump file of a running process by dropping a signal on it. But this terminates the process.
Another way to get a dump file is to pipe the pid of the process to /proc/dumper. The process keeps running!
> echo 12345 > /proc/dumper
C-code:
char pidstr[20];
int fd = open("/proc/dumper", O_RDWR);
sprintf(pidstr, "%d", getpid());
write(fd, pidstr, strlen(pidstr));
close(fd);
This will let dumper STOP the process, generate a core file, and then let the application keeps running.
