Member types and constants#

struct attach#: A tag for constructing a task_arena with attach.

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 a task_arena with default parameters.

Note

Unlike other task_arena constructors, this one automatically initializes the new task_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 initialized task_arena.
