errinfo - print errno for syscall fails. Uses DTrace.
errinfo [-a|-A|-hsvZ] [-c command]
errinfo snoops syscall failures and prints the errno value and description of the error number.
This program can help determine if applications are silently failing, providing some details on the cause.
Since this uses DTrace, only users with root privileges can run this command.
See the DTraceToolkit for further documentation under the Docs directory. The DTraceToolkit docs may include full worked examples with verbose descriptions explaining the output.
errinfo will run forever until Ctrl-C is hit.
