Some of the proc tools have been enhanced to examine process core files, as well as live processes. The proc tools are utilities that can manipulate features of the /proc file system.
The /usr/proc/bin/pstack, pmap, pldd, pflags, and pcred tools can now be applied to core files by specifying the name of the core file on the command line, similar to the way you specify a process ID to these commands.
For more information about using proc tools to examine core files, see proc(1).
