withattach
.
Member functions#
-
explicit task_arena(task_arena::attach)#
Creates an instance of
task_arena
that is connected to the internal task arena representation currently used by the calling thread. If no such arena exists yet, creates atask_arena
with default parameters.Note
Unlike other
task_arena
constructors, this one automatically initializes the newtask_arena
when connecting to an already existing arena.
-
void initialize(task_arena::attach)#
If an internal task arena representation currently used by the calling thread, the method ignores arena parameters and connects
task_arena
to that internal task arena representation. The method has no effect when called for an already initializedtask_arena
.
