       pmLookupInDom, pmRequestInDomInst, pmReceiveInDomInst - translate an instance name into an
       instance identifier


       #include <pcp/pmapi.h>

       int pmLookupInDom(pmInDom indom, const char *name);
       int pmRequestInDomInst(int ctx, pmInDom indom, const char *name);
       int pmReceiveInDomInst(int ctx);

       cc ... -lpcp


       For the instance domain indom, in the current Performance Metrics Application  Programming
       Interface  (PMAPI)  context, locate the instance with the external identification given by
       name, and return the internal instance identifier.

       Only the leading non-space characters of name will be used to identify the instance.

       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.

       pmLookupInDom will return a positive instance identifier on success.

       pmRequestInDomInst  and pmReceiveInDomInst are used by applications which must communicate
       with the PMCD asynchronously.  These functions take explicit context handle ctx which must
       refer  to  a  host  context  (i.e.  created  by  passing PM_CONTEXT_HOST to pmNewContext).
       pmRequestInDomInst sends request to translate external instance name to internal  instance
       identifier  to PMCD and returns without waiting for the response, pmReceiveInDomInst reads
       reply from PMCD. It is the responsibility of the application to make  sure  the  data  are
       ready before calling pmReceiveInDomInst to avoid blocking.


       PMAPI(3),   pmGetConfig(3),   pmGetInDom(3),   pmLookupDesc(3),   pmLookupInDomArchive(3),
       pmNameInDom(3), pcp.conf(4) and pcp.env(4).


              indom is not a valid instance domain identifier

              The external instance name is not known  for  the  instance  domain  indom  in  the
              current PMAPI context

              Context is currently in use by another asynchronous call.
