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_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.
