Description

Instances of the condition class socket-error are signaled to indicate some error associated with socket operations. Specific errors are specified by subclasses of socket-error.

Once they are connected, sockets are normally associated with a connection object, which is either a socket-stream or a async-io-state. The reader socket-error-connection can be used to get the connection object. Note that errors may arise before the connection object is created, in which case socket-error-connection will return nil.

If an error is associated with a operating system error code, the reader socket-error-code can be used to get it. In other errors, it returns nil.
