= xref:Sock.adoc[Sock]::EventsPerSock
:relfileprefix: ../
:mrdocs:

On which socket to wait for what events in `WaitMany()`. The `shared_ptr` is copied into the map to ensure that the `Sock` object is not destroyed (its destructor would close the underlying socket). If this happens shortly before or after we call `poll(2)` and a new socket gets created under the same file descriptor number then the report from `WaitMany()` will be bogus.
