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

    The Get the Offset to the Starting Position of the Most
    Significant Part of a Full Name routine returns the offset to
    the starting position of the most significant part of a full
    name. The most significant part of a full name is determined by
    the underlying network services.

    Format

      LIB$GET_FULLNAME_OFFSET  fullname, offset

1 - Returns

    OpenVMS usage:cond_value
    type:         longword (unsigned)
    access:       write only
    mechanism:    by value

2 - Arguments

 fullname

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

    Full name. The fullname argument contains the address of the
    descriptor pointing to this full name string.

    The error LIB$_INVARG is returned if fullname contains an invalid
    full name, points to a null string, or contains more than 1024
    characters. The error LIB$_INVSTRDES is returned if fullname is
    an invalid descriptor.

 offset

    OpenVMS usage:word_unsigned
    type:         word (unsigned)
    access:       write only
    mechanism:    by reference

    The offset in bytes of the starting position of the most
    significant part of fullname. The offset argument is the address
    of an unsigned word that contains this offset.

    The offset argument contains an unusable result when LIB$GET_
    FULLNAME_OFFSET returns in error.
