csx_Parse_CISTPL_LINKTARGET(9F)

Name

csx_Parse_CISTPL_LINKTARGET - parse the Link Target tuple

Synopsis

#include <sys/pccard.h>

int32_t csx_Parse_CISTPL_LINKTARGET(client_handle_t ch, tuple_t *tu,
     cistpl_linktarget_t *pt);

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).

pt

Pointer to a cistpl_linktarget_t structure which contains the parsed CISTPL_LINKTARGET tuple information upon return from this function.

Description

This function parses the Link Target tuple, CISTPL_LINKTARGET, into a form usable by PCCard drivers.

The CISTPL_LINKTARGET tuple is used to verify that tuple chains other than the primary chain are valid. All secondary tuple chains are required to contain this tuple as the first tuple of the chain.

Structure Members

The structure members of cistpl_linktarget_t are:


uint32_t   length;
char       tpltg_tag[CIS_MAX_TUPLE_DATA_LEN];

The fields are defined as follows:

length

This field indicates the number of bytes in tpltg_tag.

tpltg_tag

This field provides the Link Target tuple information.

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.
