       pmNameInDom,  pmRequestInDomName,  pmReceiveInDomName  -  translate  an
       instance identifier into an instance name


       #include <pcp/pmapi.h>

       int pmNameInDom(pmInDom indom, int inst, char **name)
       int pmRequestInDomName(int ctx, pmInDom indom, int inst)
       int pmReceiveInDomName(int ctx, char **name)

       cc ... -lpcp


       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
       performance metric.

       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.

              indom is not a valid instance domain identifier

              The instance identifier inst  is  not  known  for  the  instance
              domain indom in the current PMAPI context
