+.el \fI\\$1\f1\\$2
+..
+For the instance domain
+.IR indom ,
+in the current
+Performance Metrics Application Programming Interface (PMAPI)
+context,
+locate the instance with the external identification given by
+.IR name ,
+and return the internal instance identifier. 
+.PP
+Only the leading
+non-space characters of
+.I name
+will be used to identify the instance.
+.PP
+The value for the instance domain
+.I indom
+is typically extracted from a
+.CW pmDesc
+structure, following a call to
+.BR pmLookupDesc (3)
+for a particular performance metric.
+.PP
+.B pmLookupInDom
+will return a positive instance identifier on success.
