HELPLIB.HLB  —  LBR Routines, LBR$LOOKUP_KEY, Arguments
 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
    Name of the library key. If the library uses binary keys, the
    key_name argument is the address of the unsigned longword value
    of the key.

    If the library uses ASCII keys, the key_name argument is the
    address of a string descriptor for 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:       write only
    mechanism:    by reference
    The record file address (RFA) of the library module header.
    The txtrfa argument is the address of the 2-longword array that
    receives the RFA of the module header.

 flags

    OpenVMS usage:mask_longword
    type:         longword (unsigned)
    access:       write only
    mechanism:    by reference
    The flags argument, if present and not zero, receives the type of
    key returned. The flag bits are as follows:

    Flag Bits              Description

    LBR$SYM_WEAK = 0x1     UNIX-style weak symbol attribute
    LBR$SYM_GROUP = 0x2    Group symbol attribute

    The key returned is the highest precedent definition type
    present.
