Kernel Functions for Driverscsx_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 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.
