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

Syntax

VOID ProfileStart(
  DWORD dwUSecInterval,
  DWORD dwOptions
);

dwUSecInterval
[in] Interval, in microseconds, for each profile interrupt (sample). 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). 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). 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 as shown in the following code example: `ProfileStart( 500, PROFILE_BUFFER \| PROFILE_STARTPAUSED );` Call ProfileStart with this flag before using PROFILE_PAUSE.

None.
