 CSX_PARSE_CISTPL_BYTEORDER 9F "Dec 20, 1996"
 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 function.


 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
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.
