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.
