Send Feedback

This function starts the Windows CE instrumented kernel or Monte Carlo profiling.

VOID ProfileStart( DWORD dwUSecInterval,DWORD dwOptions );

Parameters

  • dwUSecInterval
    [in] Interval, in microseconds, for each profile interrupt (sample). Note that this can be changed depending on the target device implementation.
  • dwOptions
    [in] Profile flags. The following table shows the possible values.
    Value Description
    PROFILE_BUFFER Monte Carlo profiling; records samples to a buffer.
    PROFILE_CONTINUE Starts the profiler timer (starts/resumes the profiler sampling). You must call ProfileStart with the PROFILE_STARTPAUSED flag before using this flag.
    PROFILE_KCALL KCALL profiling; records kernel calls.
    PROFILE_OBJCALL Records object calls.
    PROFILE_PAUSE Stops the profiler timer (pauses the profiler sampling). You must call ProfileStart with the PROFILE_STARTPAUSED flag before using this flag. The first parameter to ProfileStart is ignored when using PROFILE_PAUSE.
    PROFILE_STARTPAUSED Begins profiling with the profiler timer off. Profiler control variables are initialized but the timer is not activated (no profiling samples are made). Use this flag simultaneously with PROFILE_BUFFER or PROFILE_OBJCALL according to the following code example.
    ProfileStart( 500, PROFILE_BUFFER | PROFILE_STARTPAUSED );

    You must call ProfileStart with this flag before using PROFILE_PAUSE.

Return Values

None.
