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 structure, following a call to pmLookupDesc(3) for a particular performance metric.

pmLookupInDom will return a positive instance identifier on success.
