       pmGetInDom - get instance identifiers for a performance metrics instance domain


       #include <pcp/pmapi.h>

       int pmGetInDom(pmInDom indom, int **instlist, char ***namelist);

       cc ... -lpcp


       In  the  current  Performance  Metrics  Application Programming Interface (PMAPI) context,
       locate the description of the instance domain indom, and return via instlist the  internal
       instance identifiers for all instances, and via namelist the full external identifiers for
       all instances.  The number of instances found is returned as the function value (else less
       than zero to indicate an error).

       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 resulting lists of instance identifiers (instlist and namelist), and  the  names  that
       the  elements  of namelist point to, will have been allocated by pmGetInDom with two calls
       to  malloc(3),  and  it  is  the  responsibility  of  the  caller  to  free(instlist)  and
       free(namelist) to release the space when it is no longer required.

       When  the  result of pmGetInDom is less than one, both instlist and namelist are undefined
       (no space will have been allocated, and so calling free(3) is a singularly bad idea).


              indom is not a valid instance domain identifier


       Environment variables with the prefix PCP_ are used to parameterize the file and directory
       names used by PCP.  On each installation, the file /etc/pcp.conf contains the local values
       for these variables.  The $PCP_CONF  variable  may  be  used  to  specify  an  alternative
       configuration  file,  as  described  in  pcp.conf(5).   Values  for these variables may be
       obtained programmatically using the pmGetConfig(3) function.
