Q:Task Identification ?

Q:Task Identification ?

[Margarit Nickolov]

I am using DEC Ada compiler under OpenVMS_AXP v7.1.

Is there any way to obtain task identifier which differs 
one task from the others in one program ?

see the standard package Ada.Task_Identification

That might be the answer for Ada 95, but DEC Ada is Ada 83.

Look at the package Get_Task_Info, which is part of the DEC Ada 83 distribution
for OpenVMS (and is therefore also included in the GNAT OpenVMS implementation
of Ada 95). 

GET_CURRENT_TASK_TYPE_NAME gives the (string) name of the task type

If you have multiple tasks of the same type, then you can use 
GET_CURRENT_TASK_ID which returns a unique NATURAL value to
distinguish them (e.g. convert this number to a decimal digit string).

There is no way to get the name of the task object in DEC Ada (Ada 95
does not guarantee that such a method exists either, but you can
expect Ada.Task_Identification.Image to do something useful (and
in particular with GNAT, you get a unique and usefully informative string,
that deals with arrays of tasks etc.)
