CAVEAT         top

       This  documentation  is intended for internal Performance Co-Pilot
       (PCP) developer use.

       These interfaces are not part of the PCP APIs that are  guaranteed
       to  remain  fixed  across  releases, and they may not work, or may
       provide different semantics at some point in the future.

DESCRIPTION         top

       This is a cut-down version of the archive record reading  routines
       from  libpcp,  that  writes the next physical record on the stream
       identified by f.

       The record is already formatted in rbuf, including  the  setup  of
       the  record  header length and trailer length, and rbuf must be in
       network byte-order.

       There is no checking, so the record format  must  be  correct  and
       match  the semantics of which ever physical file (metadata or data
       volume) that is associated with f.

DIAGNOSTICS AND RETURN VALUES         top

       The return value is 0 if all is well, else some  error  code  less
       than zero.
