CEL_LOG_MARKER (Compact 2013)

3/28/2014

This structure indicates the frequency of the clock used on the device.

Note

In Windows Embedded Compact 2013, the OS no longer logs this structure. Instead, use CEL_LOG_MARKER_V3.

Syntax

typedef struct __CEL_LOG_MARKER {
  DWORD dwFrequency;
  DWORD dwDefaultQuantum;
  DWORD dwVersion;
} CEL_LOG_MARKER, *PCEL_LOG_MARKER; 

Members

  • dwFrequency
    Clock frequency, in tick counts per second, used to create time stamps.
  • dwDefaultQuantum
    Quantum that will be used for each new thread that is created. The quantum can be changed at any time after the thread is created.
  • dwVersion
    Version number associated with the logging subsystem. This should always be set to 2.

Remarks

The marker should be the first item logged at the beginning of each new logging session. It provides the receiver with data used to interpret the log.

The clock frequency, dwFrequency, can be used to determine the number of seconds between events. Because all time stamps are logged in tick counts, the clock frequency can be used to convert those time stamps into seconds.
