NAME
csx_Parse_CISTPL_DEVICEGEO - parse the Device Geo tuple
SYNOPSIS

#include <sys/pccard.h> 



int32_t csx_Parse_CISTPL_DEVICEGEO(client_handle_t ch, tuple_t *tp,
 cistpl_devicegeo_t *pt);
INTERFACE LEVEL

Solaris DDI Specific (Solaris DDI)

PARAMETERS

ch

Client handle returned from csx_RegisterClient(9F).

tp

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

pt

Pointer to a cistpl_devicegeo_t structure which contains the parsed Device Geo tuple information upon return from this function.

DESCRIPTION

This function parses the Device Geo tuple, CISTPL_DEVICEGEO, into a form usable by PC Card drivers.

The CISTPL_DEVICEGEO tuple describes the device geometry of common memory partitions.

STRUCTURE MEMBERS

The structure members of cistpl_devicegeo_t are:

uint32_t info[CISTPL_DEVICEGEO_MAX_PARTITIONS].bus;
uint32_t info[CISTPL_DEVICEGEO_MAX_PARTITIONS].ebs;
uint32_t info[CISTPL_DEVICEGEO_MAX_PARTITIONS].rbs;
uint32_t info[CISTPL_DEVICEGEO_MAX_PARTITIONS].wbs;
uint32_t info[CISTPL_DEVICEGEO_MAX_PARTITIONS].part;
uint32_t info[CISTPL_DEVICEGEO_MAX_PARTITIONS].hwil;

The fields are defined as follows:

info[CISTPL_DEVICEGEO_MAX_PARTITIONS].bus

This field indicates the card interface width in bytes for the given partition.

info[CISTPL_DEVICEGEO_MAX_PARTITIONS].ebs

This field indicates the minimum erase block size for the given partition.

info[CISTPL_DEVICEGEO_MAX_PARTITIONS].rbs

This field indicates the minimum read block size for the given partition.

info[CISTPL_DEVICEGEO_MAX_PARTITIONS].wbs

This field indicates the minimum write block size for the given partition.

info[CISTPL_DEVICEGEO_MAX_PARTITIONS].part

This field indicates the segment partition subdivisions for the given partition.

info[CISTPL_DEVICEGEO_MAX_PARTITIONS].hwil

This field indicates the hardware interleave

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.
