The functionality provided by pragma Task_Info is now part of the
Ada language. The CPU aspect and the package
System.Multiprocessors offer a less system-dependent way to specify
task affinity or to query the number of processors.
Syntax
pragma Task_Info (EXPRESSION);
This pragma appears within a task definition (like pragma
Priority) and applies to the task in which it appears. The
argument must be of type System.Task_Info.Task_Info_Type.
The Task_Info pragma provides system dependent control over
aspects of tasking implementation, for example, the ability to map
tasks to specific processors. For details on the facilities available
for the version of GNAT that you are using, see the documentation
in the spec of package System.Task_Info in the runtime
library.
