NAME

       pmLookupInDom - translate an instance name into an instance identifier

C SYNOPSIS

       #include <pcp/pmapi.h>

       int pmLookupInDom(pmInDom indom, const 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 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  particu-
       lar performance metric.

       pmLookupInDom will return a positive instance identifier on success.
