Examining Core Files

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 on using proc tools to examine core files, see proc(1).

Example 16-1 Examining Core Files With proc Tools

$ ./a.out
Segmentation Fault(coredump)
$ /usr/proc/bin/pstack ./core
core './core' of 19305: ./a.out
 000108c4 main     (1, ffbef5cc, ffbef5d4, 20800, 0, 0) + 1c
 00010880 _start   (0, 0, 0, 0, 0, 0) + b8
