Description edit

X'Identity is an Ada attribute where X is any task. This attribute returns a unique identifying string (of type "Task_ID"). This string is used in some Ada tasking libraries for task identification. It may also be used directly by the user for output purposes, to determine if two tasks are the same task, etc.

Example edit

task My_Task;
task My_Other_Task;
if My_Task'Identity = My_Other_Task'Identity then
  -- Do something
end if;
