NAME         top

       pmiPutMark - write a <mark> record to a PCP archive

C SYNOPSIS         top

       #include <pcp/pmapi.h>
       #include <pcp/import.h>

       int pmiPutMark(void);

Perl SYNOPSIS         top

       use PCP::LogImport;


DESCRIPTION         top

       As   part  of  the  Performance  Co-Pilot  Log  Import  API  (see
       LOGIMPORT(3)), pmiPutMark writes a <mark> record to  the  current
       PCP  output  archive.   This is required when there is a temporal
       discontinuity between the current input source and the next input
       source, if any, and should be called  after  the  final  call  to
       pmiWrite(3)  for the current input.  If there is no next input to
       be processed or no temporal gap between sources, then the  <mark>
       record is not required.

       The <mark> record is used to signify a temporal gap, so that when
       replaying  the output PCP archive, interpolation of metric values
       should not be performed between the last timestamp in the current
       input source to the first timestamp in  the  next  input  source,
       i.e. across the <mark> record.

DIAGNOSTICS         top

       pmiPutMark returns zero on success else a negative value that can
       be turned into an error message by calling pmiErrStr(3).
