NAME
     csx_GetFirstTuple, csx_GetNextTuple - return  Card  Informa-
     tion Structure tuple

SYNOPSIS
     #include 



     int32_t csx_GetFirstTuple(client_handle_t ch, tuple_t *tu);


     int32_t csx_GetNextTuple(client_handle_t ch, tuple_t *tu);


INTERFACE LEVEL
     Solaris DDI Specific (Solaris DDI)

PARAMETERS
     ch    Client handle returned from csx_RegisterClient(9F).


     tu    Pointer to a tuple_t structure.


DESCRIPTION
     The  functions  csx_GetFirstTuple()  and  csx_GetNextTuple()
     return the first and next tuple, respectively, of the speci-
     fied type in the Card Information Structure  (CIS)  for  the
     specified socket.

STRUCTURE MEMBERS
     The structure members of tuple_t are:

       uint32_t    Socket;        /* socket number */
       uint32_t    Attributes;    /* Attributes */
       cisdata_t   DesiredTuple;  /* tuple to search for or flags */
       cisdata_t   TupleCode;     /* tuple type code */
       cisdata_t   TupleLink;     /* tuple data body size */



     The fields are defined as follows:

     Socket                 Not used in Solaris, but  for  porta-
                            bility   with   other  Card  Services
                            implementations, it should be set  to
                            the logical socket number.


     Attributes             This field is bit-mapped. The follow-
                            ing bits are defined:

                            TUPLE_RETURN_LINK

                                Return link tuples  if  set.  The
                                following  are  link  tuples  and
                                will only  be  returned  by  this
                                function if the TUPLE_RETURN_LINK
                                bit in the  Attributes  field  is
                                set:

                                       CISTPL_LONGLINK_A   CISTPL_LINKTARGET
                                       CISTPL_LONGLINK_C   CISTPL_NO_LINK
                                       CISTPL_LONGLINK_CB  CISTPL_END



                            TUPLE_RETURN_IGNORED_TUPLES

                                Return  ignored  tuples  if  set.
                                Ignored  tuples  will be returned
                                by   this   function    if    the
                                TUPLE_RETURN_IGNORED_TUPLES   bit
                                in the Attributes field  is  set,
                                see  tuple(9S)  for more informa-
                                tion. The CIS is parsed from  the
                                location  setup  by  the previous
                                csx_GetFirstTuple()            or
                                csx_GetNextTuple() request.



     DesiredTuple           This  field  is   the   tuple   value
                            desired. If it is RETURN_FIRST_TUPLE,
                            the very first tuple of  the  CIS  is
                            returned  (if  it  exists).  If  this
                            field is  set  to  RETURN_NEXT_TUPLE,
                            the  very  next  tuple  of the CIS is
                            returned  (if  it  exists).  If   the
                            DesiredTuple field is any other value
                            on entry, the CIS is searched  in  an
                            attempt   to  locate  a  tuple  which
                            matches.


     TupleCode,TupleLink    These fields are the values  returned
                            from the tuple found. If there are no
                            tuples on the card,  CS_NO_MORE_ITEMS
                            is returned.

Kernel Functions for Drivers                csx_GetFirstTuple(9F)



     Since  the  csx_GetFirstTuple(),   csx_GetNextTuple(),   and
     csx_GetTupleData(9F)  functions  all  share the same tuple_t
     structure, some fields in the tuple_t structure  are  unused
     or reserved when calling this function and these fields must
     not be initialized by the client.

RETURN VALUES
     CS_SUCCESS                 Successful operation.


     CS_BAD_HANDLE              Client handle is invalid.


     CS_NO_CARD                 No PC Card in socket.


     CS_NO_CIS                  No  Card  Information   Structure
                                (CIS) on PC card.


     CS_NO_MORE_ITEMS           Desired tuple not found.


     CS_UNSUPPORTED_FUNCTION    No PCMCIA hardware installed.


CONTEXT
     These functions may be called from user or kernel context.
