/sys$common/syshlp/helplib.hlb TCPIP Services, Programming Interfaces, Sockets API, getnetbyname(), Description  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    This function finds the first network record in the networks
    database with the given name or alias.
    The getnetbyaddr() and getnetbyname()  functions use a common
    static area for their return values. Subsequent calls to any of
    these functions overwrite previously returned network entries.
    You must make a copy of the network entry if you want to save it.
