     tion Structure tuple

SYNOPSIS

     #include <sys/pccard.h>

     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  portability  with  other
           Card Services implementations, it should be set to the
           logical socket number.

     Attributes
           This field  is  bit-mapped.  The  following  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_NULL    CISTPL_LONGLINK_MFC
                      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  Attri-
                 butes field is set, see tuple(9S)for more infor-
                 mation. 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.

     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.
