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)

ARGUMENTS

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 memorylike 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_HIGH	Big 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) on PC Card.

CS_UNSUPPORTED_FUNCTION

No PCMCIA hardware installed.

CONTEXT

This function may be called from user or kernel context.
