* In addition to recording a routine's failing status, it offers
* logging of routines for call stack tracing.
* EXITCODE should be used only in routines that return a true errno value, as
* that value will be formatted to a displayable errno string. Routines that
* return regular int status that are not true errno should not set EXITCODE.
* If you want to log routine tracing, you can add EXITCODE(0) to any routine.
* NFS extended the EXITCODE with EXITCODE2 to record either the routine's
* exit errno status or the nd_repstat.
