## Synopsis

## Description

This function returns the IP and/or PORT of the remote injection source. In particular, it returns the component of the sockaddr, in human-readable form, as indicated by the flag. The value of the flag parameter can be `ip`, `port` or `all`. The default input parameter is `all`. That is, if `flag` is `nil`, then this returns the same string as if `all` was passed as the parameter.
