How is the ulimit -c unlimited command used and what does it do?

I'm helping to write a program right now, and on windows, the program works fine. On the mac, after changing the framework directory to the only suitable location, I'm getting this error:

run:

A fatal error has been detected by the Java Runtime Environment:

If you have some bug (unexpected error scenarios) in your program and it is resulting in crashing your program, you should be able to debug why the program has crashed. For this purpose the Operating system will copy process stack into a file called core dump file.

ulimit , is a system command.

ulimit -c unlimited, command used to set the core dump file size to unlimited. Instead of unlimited you can specify the maximum limit of the core dump file size also.

for more information type man ulimit
