| Produced file is equivalent to a kernel produced core file as if the process |
| crashed (and if <kbd>ulimit -c</kbd> were used to set up an appropriate core dump |
| limit). Unlike after a crash, after <code>gcore</code> the program remains |

| If not specified, the file name defaults to <samp>core.<var>pid</var></samp>, |
