VMS Help RTL Routines, DNS$, DNS$CVT_DNSADDRESS_TO_NODENAME  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    The Convert a DNS Address to a Node Name routine takes a DNS
    address and returns a DECnet Phase IV node name.

    Format

      DNS$CVT_DNSADDRESS_TO_NODENAME

        dnsaddress ,nodename ,resulting-length

    Arguments

 dnsaddress
    OpenVMS Usage: char_string
    type:          character string
    access:        read only
    mechanism:     by descriptor

    The DNS address. The dnsaddress argument is the address of a
    descriptor pointing to the DNS address.

 nodename
    OpenVMS Usage: char_string
    type:          character string
    access:        write only
    mechanism:     by descriptor

    The DECnet Phase IV node name. The nodename argument is the
    address of a descriptor pointing to the Phase IV node name. The
    memory buffer referenced by the DSC$A_POINTER portion of this
    descriptor must be large enough to contain the entire Phase IV
    node name string, which is up to six bytes long.

 resulting-length
    OpenVMS Usage: word_unsigned
    type:          word (unsigned)
    access:        write only
    mechanism:     by reference

    The length of the node name (in bytes) after conversion. The
    resulting-length argument is a word containing the length of the
    node name (in bytes) after conversion.
