    _________________________________________________________________________
    Argument                         Description
    _________________________________________________________________________
    isfd                             File descriptor identifying the ISAM
                                     file whose index is being deleted.
    keydesc                          Name of the structure defining the index
                                     to be deleted.

    Any index may be removed except the primary index.

    The file must be opened in exclusive mode or the operation fails. On suc-
    cess, isdelindex returns 0.  Otherwise, it returns -1 and sets iserrno to
    indicate the error.
