Generate a core dump of a running program with process ID pid.
Produced file is equivalent to a kernel produced core file as if the
process crashed (and if "ulimit -c" were used to set up an
appropriate core dump limit). Unlike after a crash, after gcore the
program remains running without any change.
The full documentation for GDB is maintained as a Texinfo manual. If
the "info" and "gdb" programs and GDB's Texinfo documentation are
properly installed at your site, the command
should give you access to the complete manual.
