 library_index

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

 key_name

    OpenVMS usage:longword_unsigned
    type:         longword (unsigned)
    access:       read only
    mechanism:    by reference
    The key_name argument is the address of the string descriptor
    pointing to the key with the following argument characteristics:

    Argument
    Characteristics        Entry

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

 txtrfa

    OpenVMS usage:vector_longword_unsigned
    type:         longword (unsigned)
    access:       read only
    mechanism:    by reference
    The module's record file address (RFA) of the library module
    header. The txtrfa argument is the address of the 2-longword
    array that specifies the RFA of the module header.

    type:         longword (unsigned)
    access:       write only
    mechanism:    by reference
    The address of a longword to receive the symbol types found
    for the specified module (txtrfa). The return type bits are as
    follows:

       LBR$M_SYM_NGG = 1
       LBR$M_SYM_UXWK = 2
       LBR$M_SYM_GG = 4
       LBR$M_SYM_GUXWK = 8
