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

NAME
       csx_Parse_CISTPL_BYTEORDER - parse the Byte Order tuple

SYNOPSIS
       #include <sys/pccard.h>

       int32_t csx_Parse_CISTPL_BYTEORDER(client_handle_t ch, tuple_t *tu, cistpl_byteorder_t *cbo);

INTERFACE LEVEL
       Solaris DDI Specific (Solaris DDI)

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

       tu	Pointer to a tuple_t structure (see tuple(9S)) returned by a call to csx_GetFirstTuple(9F) or csx_GetNextTuple(9F).

       cbo	Pointer to a cistpl_byteorder_t structure which contains the parsed CISTPL_BYTEORDER tuple information upon return from this func-
		tion.

DESCRIPTION
       This function parses the Byte Order tuple, CISTPL_BYTEORDER, into a form usable by PC Card drivers.

       The CISTPL_BYTEORDER tuple shall only appear in a partition tuple set for a memory-like partition.  It specifies two parameters: the  order
       for multi-byte data, and the order in which bytes map into words for 16-bit cards.

STRUCTURE MEMBERS
       The structure members of cistpl_byteorder_t are:

       uint32_t     order;     /* byte order code */
       uint32_t     map;       /* byte mapping code */

       The fields are defined as follows:

       order	       This field specifies the byte order for multi-byte numeric data.

		       TPLBYTEORD_LOW

			   Little endian order

		       TPLBYTEORD_VS

			   Vendor specific

       map	       This field specifies the byte mapping for 16-bit or wider cards.

		       TPLBYTEMAP_LOW

			   Byte zero is least significant byte

		       TPLBYTEMAP_HIGH

			   Byte zero is most significant byte

		       TPLBYTEMAP_VS

			   Vendor specific mapping

RETURN VALUES
       "small and bold">CS_SUCCESS     Successful operation.

       CS_BAD_HANDLE		       Client handle is invalid.

       CS_UNKNOWN_TUPLE 	       Parser does not know how to parse tuple.

       CS_NO_CARD		       No PC Card in socket.

       CS_NO_CIS		       No Card Information Structure (CIS) PC Card.

       CS_UNSUPPORTED_FUNCTION	       No PCMCIA hardware installed.

CONTEXT
       This function may be called from user or kernel context.
