PMPRINTVALUE(3) 					     Library Functions Manual						   PMPRINTVALUE(3)

NAME
pmPrintValue - print a performance metric value C SYNOPSIS
#include <stdio.h> #include <pcp/pmapi.h> void pmPrintValue(FILE *f, int valfmt, int type, const pmValue *val, int minwidth); cc ... -lpcp DESCRIPTION
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).

PMAPI(3), pmAtomStr(3), pmConvScale(3), pmExtractValue(3), pmFetch(3), pmLookupDesc(3), pmTypeStr(3) and pmUnitsStr(3). Performance Co-Pilot PCP PMPRINTVALUE(3)

NAME
pmTypeStr, pmTypeStr_r - convert a performance metric type into a string C SYNOPSIS
#include <pcp/pmapi.h> const char *pmTypeStr(int type); char *pmTypeStr_r(int type, char *buf, int buflen); cc ... -lpcp DESCRIPTION
Given a performance metric type, pmTypeStr produces a terse ASCII equivalent, appropriate for use in error and diagnostic messages. The pmTypeStr_r function does the same, but stores the result in a user-supplied buffer buf of length buflen, which should have room for at least 20 bytes. The value for type is typically extracted from a pmDesc structure, following a call to pmLookupDesc(3) for a particular performance metric. Examples are 32 (for type equals PM_TYPE_32), U64 (for type equals PM_TYPE_U64), AGGREGATE (for type equals PM_TYPE_AGGREGATE), etc. The string value result for pmTypeStr is held in a single static buffer, so the returned value is only valid until the next call to pmType- Str. NOTES
pmTypeStr returns a pointer to a static buffer and hence is not thread-safe. Multi-threaded applications should use pmTypeStr_r instead. SEE ALSO
