csx_GetFirstTuple(9F)	 Kernel Functions for Drivers	 csx_GetFirstTuple(9F)

NAME
       csx_GetFirstTuple, csx_GetNextTuple - return Card Information 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 specified 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
	       Attributes  field  is  set, see tuple(9S) for more information.
	       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_GetTupleā€
       Data(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.
