acgreek/coredump

segv handler that allows one to define where core dump will be stored

coredump

This little library provides an api to replace the default segv handler with one that will generate a core regardless of the system wide Linux kernel/ulimit settings.

void setup_core_dump_handler(const char * path);

sets up the core dump handler. Path is the full path to where the core dump will written if a segv signal is received.

void fini_core_dump_handler(void);

you should call this before program termination

Example

#include "coredump.h"

int main(int argc, char * argv[]) {
  setup_core_dump_handler("/tmp/example_core");
  
  .... program body here ....
  
  fini_core_dump_handler();
  return 0;
}

or with c++, you can use this conviencent wrapper and not worry about the clean up

#include "coredump.h"

int main(int argc, char * argv[]) {
  CoreDumpHandler core_dump_handler("/tmp/example_core");
  .... program body here ....
  
  return 0;
}
