.SH DESCRIPTION
\fIDumpcore\fR executes the same code that FS executes in order to
generate a core dump of a currently running process, identified by
endpoint number. Obtain an endpoint number by using the F1 debug
dump, or ps with -E option.
The \fBdumpcore\fR utility generates a core file for a running process, based
on that process's process ID (\fIpid\fP). The resulting core file will be
stored under the name "core" in the current working directory. Any previous
file with that name will be overwritten.
.PP
The resulting core file can be used with for example
.BR mdb (1).
.SH BUGS
\fIDumpcore\fR has duplicate code with FS, and has to be started with
the service command.
The process of generating the core file is currently very rudimentary, and
the generated core file does not contain for example memory mapped areas.
.SH "SEE ALSO"
.BR ps (1).
.BR mdb (1).
