* vtuneapi.h 03-21-2001
* Intel Corporation
*
* This header file describes VTune api's which are exported by vtuneapi.dll.
*
* To use these api's, include this header file and either link with vtuneapi.lib or load
* vtuneapi.dll at runtime.
*
* VTune API's
* -----------
*
* VOID VTPause(void) and VOID VTResume(void)
*
* VTPause and VTResume pause or resume data collection during a VTune Sampling, Counter Monitor, or Callgraph activity.
*
* If VTPause is called while a VTune Sampling collection is active, a flag is set which
* suspends collection of PC samples on the current machine. Collection of PC samples
* can be resumed by calling VTResume which clears the flag. The overhead to set and clear the flag
* is very low, so the VTPause and VTResume can be called at a high frequency.
*
* If VTPause is called while a VTune Callgraph collection is active, Callgraph data collection
* is paused for the current process. Callgraph data collection for the current process can
* be resumed by calling VTResume.
*
* If VTPause is called while a VTune Counter Monitor collection is active, Counter Monitor data collection
* is paused. Counter Monitor data collection can be resumed by calling VTResume.
*
* VTPause and VTResume can be safely called when the Sampling, Counter Monitor, and Callgraph collectors are not active.
* In this case, the VTPause and VTResume do nothing.
*
* Note:
*
* VTune Sampling, Counter Monitor, and Callgraph activities are typically started with the VTune application.
* The VTune GUI allows Sampling, Counter Monitor, and Callgraph activities to be started in "Pause" mode
* which suspends data collection until a VTResume is called.
* Data collection can also be paused and resumed by the Pause/Resume button in the VTune GUI.
* See VTune onlilne help for more details.
