Function Documentation

unsigned int TRC_differMonitor (  TRC_Monitor *  old, TRC_Monitor *  new, TRC_Top *  top )

Take the difference between monitor snapshots. Parameters: old  (in) Record at start of sampling period new  (in) Record at end of sampling period top  (out) Differential monitor record Return values: TRC_MONMATCH  Monitor record serial numbers do not match TRC_NOCALC  Time mis-ordered (or zero), cannot calculate TRC_NOOLDMON  Older monitor buffer not valid for differencing TRC_NOTMON  Invalid monitor record TRC_PARMNULL  NULL parameter detected TRC_SUCCESS  Success TRC_differMonitor() knows how to take the "difference" between two monitor records and place a summary in the output TRC_Top structure.

unsigned int TRC_sizeofMonitor (  void   )

The size of a buffer to accomodate a task monitor snapshot. Return values: x  Size of a buffer to hold a task monitor snapshot

unsigned int TRC_sizeofTop (  void   )

The size of a buffer to accomodate a task monitor snapshot. Return values: x  Size of a buffer to hold a task monitor snapshot

unsigned int TRC_snapMonitor (  TRC_Monitor *  mon  )

Snapshot the task monitor structure. Parameters: mon  (out) Where to put the results Return values: TRC_PARMNULL  NULL parameter detected TRC_NOTINIT  Trace system not in state initialized TRC_SUCCESS  Success TRC_snapMonitor() copies the current monitor contents of the task to name table to a lookaside monitor buffer.
