how to log segmentation fault in forked child


if i do a fork();
and my child does a segmentation fault
how can i recognize this?

as far as i know if a child from the apache server does a segfault you get a line in the apache error log

and i know from windows you can perform your own crash functions if your app crashes so you can email yourself a error report

is something similiar possible under linux?
how do i recognize a segfault
is it possible to get a backtrace?

// example signal handler for segfaults
void handle_sigsegv(int segnum)
  fprintf(stderr,"Signal SIGSEGV (%d) received", signum);
// install a handler for SIGSEGV in a part of your code
  fprintf(stderr,"Could not install SIGSEGV handler");
  return -1;
