C SYNOPSIS

13       int minwidth)

DESCRIPTION

18       The value of a single performance metric  (as  identified  by  val)  is
19       printed on the standard I/O stream identified by f.
20
21       The  value  of  the  performance metric is interpreted according to the
22       format of val as defined by valfmt (from a pmValueSet within a pmResult
23       structure;  see  pmFetch(3)) and the generic description of the metrics
24       type passed in via type.
25
26       The value for type is typically extracted from a pmDesc structure, fol‐
27       lowing a call to pmLookupDesc(3) for a particular performance metric.
28
29       The output will be optionally padded to be at least minwidth characters
30       wide.
31
32       pmPrintValue is most useful for displaying values of  performance  met‐
33       rics  from  pmFetch(3) (which returns a set of valfmt and val pairs for
34       each requested metric), based upon the metrics type  as  returned  from
35       pmLookupDesc(3).
