Описание (Description)

Provided that the current Performance Metrics Application
       Programming Interface (PMAPI) context is associated with a set of
       archive logs, pmNameInDomArchive will scan the union of all the
       instance domain metadata for the instance domain indom, locate
       the first instance with the internal instance identifier given by
       inst, and return the full external instance identification via
       name.

       This routine is a specialized version of the more general PMAPI
       routine pmNameInDom.

       The value for the instance domain indom is typically extracted
       from a pmDesc structure, following a call to pmLookupDesc(3) for
       a particular performance metric.

       The space for the value of name will have been allocated in
       pmNameInDomArchive with malloc(3), and it is the responsibility
       of the caller to free(3) the space when it is no longer required.

       pmNameInDomArchive returns zero on success.

              set of archive logs
