Detailed Description

template<typename Handler>
class asioext::associated_allocator< Handler >

Helper trait to obtain the allocator associated with a handler.

Retrieves an Allocator that is used to allocate memory tied to the handler's asynchronous operation.

Supports the associated_allocator trait introduced by the Networking TS / Asio 1.11.0+, as well as Asio's memory allocation hooks (which this trait will wrap in a hook_allocator)

Note

This trait is useful for libraries / applications that need to deal with both types of allocation customizations.
