Detailed Description

template<class T>
class caf::async::consumer_resource< T >

Grants read access to the first consumer that calls open on the resource.

Cancels consumption of items on the buffer if the resources gets destroyed before opening it.

try_open()

template<class T >

buffer_ptr caf::async::consumer_resource< T >::try_open

(

)

Tries to open the resource for reading from the buffer.

The first open wins on concurrent access.

Returns

a pointer to the buffer on success, nullptr otherwise.
