+.SH DESCRIPTION

+.ie t \f(CW\\$1\f1\\$2
+.el \fI\\$1\f1\\$2
+..
+The value of a single performance metric (as identified by
+.IR val )
+is printed on the standard I/O stream identified by
+.IR f .
+.PP
+The value of the performance metric is interpreted according to the format of
+.I val
+as 
+defined by
+.I valfmt
+(from a
+.CW pmValueSet
+within a
+.CW pmResult
+structure; see
+.BR pmFetch (3))
+and the generic description of the metrics type
+passed in via
+.IR type .
+.PP
+The value for
+.I type
+is typically extracted from a
+.CW pmDesc
+structure, following a call to
+.BR pmLookupDesc (3)
+for a particular performance metric.
+.PP
+The output will be optionally padded to be at least
+.I minwidth
+characters wide.
+.PP
+.B pmPrintValue
+is most useful for displaying values of performance metrics from
+.BR pmFetch (3)
+(which returns a set of
+.I valfmt
+and
+.I val
+pairs for each requested metric), based upon the
+metrics type as returned from
+.BR pmLookupDesc (3).
