CSX_PARSE_CISTPL_LINKTARGET(9F) Kernel Functions for Drivers

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

illumos DDI Specific (illumos 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 PC Card 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.
