C SYNOPSIS#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)

DESCRIPTIONFor 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.
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
Context is currently in use by another asynchronous call
