For the instance domain indom, in the current Performance Metrics
Application Programming Interface (PMAPI) context, locate the instance
with the internal instance identifier given by inst, and return the
full external instance identification via name.
The value for the instance domain indom is typically extracted from a
pmDesc structure, following a call to pmLookupDesc(3) for a particular
The space for the value of name will have been allocated in pmNameInDom
with malloc(3C), and it is the responsibility of the caller to free(3C)
the space when it is no longer required.
pmNameInDom returns zero on success.
pmRequestInDomName and pmReceiveInDomName are used by applications
which must communicate with the PMCD asynchornously. These functions
take explict context handle ctx which must refer to a host context
(i.e. creared by passing PM_CONTEXT_HOST to pmNewContext).
pmRequestInDomName sends request to translate internal instance
identifier to external instance name to PMCD and returns immediately,
pmReceiveInDomName reads reply from PMCD without waiting, it is the
responsibility of the application to make sure the data are ready
before calling pmReceiveInDomName.
