       This documentation is intended for internal Performance Co-Pilot (PCP) developer use.

       These interfaces are not part of the PCP APIs that are guaranteed to remain fixed across releases, and at
       some point in the future they may not work or may provide different semantics.

__pmLogWriteMark  appends  a  <mark>  record  to the current data file of a PCP archive.  A <mark> record
       indicates a discontinuity in the time series of logged data in the  archive,  see  PCPIntro(1)  for  more
       information.

       The  timestamp  of  the  <mark> record is given by last_stamp optionally incremented by inc unless inc is
       NULL (in which case no increment is done).

       The current data volume's I/O stream and the archive version (determines the format of the <mark> record)
       are determined from acp.

       The return value is 0 if all is well, else some error code less than zero that  can  be  turned  into  an
       error message by calling pmErrStr(3).
