VMS Help TCPIP Services, Programming Interfaces, Sockets API, inet_ntoa(), Description  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    This function converts an internet address into an ASCII (null-
    terminated) string that represents the address in standard
    internet dotted-decimal format.
    Because the string is returned in a static buffer that is
    overwritten by subsequent calls to inet_ntoa(), you should copy
    the string to a safe place.
