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

       The instance domain identified by lidp is sorted in ascending  in‐
       ternal instance identifier value.  Both the lidp->instlist[] array
       and the corresponding lidp->namelist[] array are sorted.

       Since  instance  domains  are usually sorted (at their source by a
       PMDA), a bubble sort is used.  This means that if  the  caller  is
       unsure  if  the  instance domain is sorted (but it actually is al‐
       ready sorted), then calling pmaSortInDom is as fast as checking if
       the instance domain is sorted, so when in doubt, simply call  pma‐
       SortInDom.

DIAGNOSTICS AND RETURN VALUES         top

       None.
