folly::ShutdownSocketSet

Synopsis

Declared in <folly/io/ShutdownSocketSet.h>

class ShutdownSocketSet;

Name	Description
`ShutdownSocketSet` [constructor]	Constructors
`operator=` [deleted]	Deleted copy assignment; the set is non-copyable.
`add`	Add an already open socket to the list of sockets managed by ShutdownSocketSet. You MUST close the socket by calling ShutdownSocketSet::close (which will, as a side effect, also handle EINTR properly) and not by calling close() on the file descriptor.
`close`	Close a socket managed by ShutdownSocketSet. Returns the same return code as ::close() (and sets errno accordingly).
`remove`	Remove a socket from the list of sockets managed by ShutdownSocketSet. Note that remove() might block! (which we lamely implement by sleep()-ing) in the extremely rare case that the fd is currently being shutdown().
`shutdown`	Shut down a socket. If abortive is true, we perform an abortive shutdown (send RST rather than FIN). Note that we might still end up sending FIN due to the rather interesting implementation.
`shutdownAll`	Immediate shutdown of all connections. This is a hard-hitting hammer; all reads and writes will return errors and no new connections will be accepted.

Name	Description
`tryGetShutdownSocketSet`	Returns the process-global shutdown socket set, if one has been installed.
`tryGetShutdownSocketSetFast`	Returns the process-global shutdown socket set using a read-mostly pointer.
