VMS Help LBR Routines, LBR$INI_CONTROL, Arguments  *Conan The Librarian (sorry for the slow response - running on an old VAX)

 library_index

    OpenVMS usage:longword_unsigned
    type:         longword (unsigned)
    access:       write only
    mechanism:     by reference
    Library control index returned by the LBR$INI_CONTROL routine.
    The library_index argument is the address of a longword that is
    to receive the index.

 func

    OpenVMS usage:longword_unsigned
    type:         longword (unsigned)
    access:       read only
    mechanism:    by reference
    Library function to be performed. The func argument is the
    address of the longword that contains the library function.
    Valid functions are LBR$C_CREATE, LBR$C_READ, and LBR$C_UPDATE.
    Each programming language provides an appropriate mechanism for
    accessing these symbols.

 type

    OpenVMS usage:longword_unsigned
    type:         longword (unsigned)
    access:       read only
    mechanism:    by reference
    Library type. The type argument is the address of the longword
    containing the library type. Valid library types include the
    following:

    o  LBR$C_TYP_OBJ (VAX object)

    o  LBR$C_TYP_SHSTB (VAX shareable image)

    o  LBR$C_TYP_EOBJ (Alpha object)

    o  LBR$C_TYP_ESHSTB (Alpha shareable image)

    o  LBR$C_TYP_MLB (macro)

    o  LBR$C_TYP_HLP (help)

    o  LBR$C_TYP_TXT (text)

    o  LBR$C_TYP_UNK (unknown)

    o  LBR$C_TYP_NCS (NCS library)

    o  For user-developed libraries, a type in the range of LBR$C_
       TYP_USRLW through LBR$C_TYP_USRHI.

 namblk

    OpenVMS usage:nam
    type:         longword (unsigned)
    access:       read only
    mechanism:    by reference
    OpenVMS RMS name block (NAM). The namblk argument is the address
    of a variable-length data structure containing an RMS NAM block.
    The LBR$OPEN routine fills in the information in the NAM block
    so it can be used later to open the library. If the NAM block
    has this file identification in it from previous use, the
    LBR$OPEN routine uses the open-by-NAM block option. This argument
    is optional and should be used if the library will be opened
    many times during a single run of the program. For a detailed
    description of RMS NAM blocks, see the OpenVMS Record Management
    Services Reference Manual.
