Need signal handler that will rename core file.

[David J. McVicar]

	How can a process, while handling a core dumping signal, leave
a core file in the current working directory (or other directory, if
possible) that is not named 'core'.  It is often desirable to have a
uniquely named core file, (ex. core.process.pid) for tracking problems and
debugging executables in a production environment.  I have experimented with 
signal handlers that will create a "dummy" core file in the current directory 
when a signal is encountered, then set up a hard link to that core file using 
the unique name.  But, upon process termination, our UNIX kernel (Ultrix 2.2) 
will always create the "real" core using a different inode number than the 
"dummy" core inode, resulting in a broken link with the unique name.

	The problem get's easier when you have a parent process that can
come around after a child dies and rename it's childs core, but how can this
be done in a process with no parent?

	Thanks in advance for any responses.
