PMPRINTVALUE(3) Library Functions Manual PMPRINTVALUE(3)
pmPrintValue - print a performance metric value
#include <stdio.h>
#include <pcp/pmapi.h>
void pmPrintValue(FILE *f, int valfmt, int type, const pmValue *val,
int minwidth);
cc ... -lpcp
The value of a single performance metric (as identified by val) is
printed on the standard I/O stream identified by f.
The value of the performance metric is interpreted according to the
format of val as defined by valfmt (from a pmValueSet within a
pmResult structure; see pmFetch(3)) and the generic description of
the metrics type passed in via type.
The value for type is typically extracted from a pmDesc structure,
following a call to pmLookupDesc(3) for a particular performance
metric.
The output will be optionally padded to be at least minwidth
characters wide.
pmPrintValue is most useful for displaying values of performance
metrics from pmFetch(3) (which returns a set of valfmt and val pairs
for each requested metric), based upon the metrics type as returned
from pmLookupDesc(3).
