       pmInDomStr  -  convert  a performance metric instance domain identifier
       into a string


       #include <pcp/pmapi.h>

       const char *pmInDomStr(pmInDom indom)

       cc ... -lpcp


       For use in error and diagnostic messages,  return  a  ’human  readable’
       version of the specified instance domain identifier.

       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.

       Internally, an instance domain identifier is encoded as follows;

            typedef struct {
                int             pad:2;
                unsigned int    domain:8;        /* the administrative PMD */
                unsigned int    serial:22;       /* unique within PMD */
            } __pmInDom_int;

       pmInDomStr  returns  a  string  with  each  of  the  domain  and serial
       subfields appearing as decimal numbers, separated by periods.

       The string value is held in a single static  buffer,  so  the  returned
       value is only valid until the next call to pmInDomStr.


       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(4).  Values for these variables may be
       obtained programatically using the pmGetConfig(3) function.
