Task start |
Represents the location and associated call stack when the task began execution. |
Example
void main()
{
ANNOTATE_TASK_BEGIN(name_task1); // Begin task
ANNOTATE_TASK_END();
}
This example does not execute a ANNOTATE_SITE_BEGIN(sitename)/ANNOTATE_SITE_END() annotation pair required to wrap the execution of a task ANNOTATE_TASK_BEGIN(taskname)/ANNOTATE_TASK_END() annotation pair.
Possible Correction Strategies
Always execute an ANNOTATE_SITE_BEGIN(sitename) annotation before executing an ANNOTATE_TASK_BEGIN(taskname) annotation. You may need to add an ANNOTATE_SITE_BEGIN(sitename) /ANNOTATE_SITE_END() annotation pair in the same function, or in some calling function.
An orphaned task is effectively ignored by the Suitability and Dependencies tool analysis, so you should fix the orphaned task code and run the Suitability and Dependencies tools again.
