Question Why program received SIGQUIT quited but did NOT generate the core file ????

The Advance Programming in Univ Environment book said programs received SIGQUIT default to terminate and generate a core file.

I coded a simple program with only one line code: sleep(20);

Then i ran the program.
$ ./test

Program was waiting there for 20 seconds, so I typed the terminal quit key(Control-backslash).

The program terminated as expected.
But there's no CORE FILE generated on the current directory ?

why did this happened?

Any helps would be greatly appreciated.

Tku IA.

It could be that you core file size limit value is set to 0. Do a "ulimit -a" and see what the core file size reports. If zero, then do a "ulimit -c unlimited" to disable core limits for that shell. NOTE: If you are running multiple windows/multiple shells you must reset the ulimit values for each shell, or you could put the ulimit command into your local .rc file to have it automatically executed every time you create a new window.
