* 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.
