PMIERRSTR(3) Library Functions Manual PMIERRSTR(3)NAME
pmiErrStr - convert a LOGIMPORT error code into a string
C SYNOPSIS
#include <pcp/pmapi.h>
#include <pcp/import.h>
const char *pmiErrStr(int code);
char *pmiErrStr_r(int code, char buf, int buflen);
cc ... -lpcp_import -lpcp
Perl SYNOPSIS
use PCP::LogImport;
pmiErrStr($code);
DESCRIPTION
As part of the Performance Co-Pilot Log Import API (see LOGIMPORT(3)), pmiErrStr translates error codes returned from the other routines in
the Log Import library into printable error messages.
code would normally have a negative value. As a special case, if code is -1 then the error code returned from the last routine called in
the LOGIMPORT library for this context will be used.
The pmiErrStr_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 PMI_MAXERRMSGLEN bytes.
The set of possible error codes and messages is all those defined by pmErrStr(3) and PCPIntro(3), plus the additonal ones defined in
<pcp/import.h> with error code names of the form PMI_ERR_....
DIAGNOSTICS
None.

PMIPUTVALUEHANDLE(3) Library Functions Manual PMIPUTVALUEHANDLE(3)NAME
pmiPutValueHandle - add a value for a metric-instance pair via a handle
C SYNOPSIS
#include <pcp/pmapi.h>
#include <pcp/impl.h>
#include <pcp/import.h>
int pmiPutValueHandle(int handle, const char *value);
cc ... -lpcp_import -lpcp
Perl SYNOPSIS
use PCP::LogImport;
pmiPutValueHandle($handle, $value);
DESCRIPTION
As part of the Performance Co-Pilot Log Import API (see LOGIMPORT(3)), pmiPutValueHandle adds a single value to the current output record
for a given metric and instance, using the handle defined by an earlier call to pmiGetHandle(3).
The value should be in a format consistent with the metric's type as defined in the call to pmiAddMetric(3).
No data will be written until pmiWrite(3) is called, so multiple calls to pmiPutValueHandle or pmiPutValue(3) are typically used to accumu-
late data values for several metric-instance pairs before calling pmiWrite(3).
DIAGNOSTICS
pmiPutValueHandle returns zero on success else a negative value that can be turned into an error message by calling pmiErrStr(3).
SEE ALSO LOGIMPORT(3), pmiErrStr(3), pmiGetHandle(3), pmiPutResult(3), pmiPutValue(3) and pmiWrite(3).
