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.
