NAME

       pmNameInDom - translate an instance identifier into an instance name

C SYNOPSIS

       #include <pcp/pmapi.h>

       int pmNameInDom(pmInDom indom, int inst, char **name);

       cc ... -lpcp

DESCRIPTION

       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(3),
       and  it  is  the  responsibility  of  the caller to free(3) the space when it is no longer
       required.

       pmNameInDom returns zero on success.

DIAGNOSTICS

       PM_ERR_INDOM
              indom is not a valid instance domain identifier

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