CSX_PARSE_CISTPL_FUNCID(9F) Kernel Functions for Drivers

NAME

csx_Parse_CISTPL_FUNCID - parse Function Identification tuple

SYNOPSIS

#include <sys/pccard.h>

int32_t csx_Parse_CISTPL_FUNCID(client_handle_t ch, tuple_t *tu,
cistpl_funcid_t *cf);

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).

cf
Pointer to a cistpl_funcid_t structure which contains the
parsed CISTPL_FUNCID tuple information upon return from this
function.

DESCRIPTION

This function parses the Function Identification tuple,
CISTPL_FUNCID, into a form usable by PC Card drivers.

The CISTPL_FUNCID tuple is used to describe information about the
functionality provided by a PC Card. Information is also provided to
enable system utilities to decide if the PC Card should be configured
during system initialization. If additional function specific
information is available, one or more function extension tuples of
type CISTPL_FUNCE follow this tuple (see csx_Parse_CISTPL_FUNCE(9F)).

STRUCTURE MEMBERS

The structure members of cistpl_funcid_t are:

uint32_t function; /* PC Card function code */
uint32_t sysinit; /* system initialization mask */

The fields are defined as follows:
