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;
}
