NAME

csx_Parse_CISTPL_GEOMETRY - parse the Geometry tuple

SYNOPSIS

#include <sys/pccard.h>
int32_t csx_Parse_CISTPL_GEOMETRY(client_handle_t ch, tuple_t *tu,


     cistpl_geometry_t *pt);

illumos DDI Specific (illumos DDI)

Client handle returned from csx_RegisterClient(9F).

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

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

This function parses the Geometry tuple, CISTPL_GEOMETRY, into a form usable by PC Card drivers.

The CISTPL_GEOMETRY tuple indicates the geometry of a disk-like device.

The structure members of cistpl_geometry_t are:



  uint32_t     spt;


   uint32_t     tpc;


   uint32_t     ncyl;

The fields are defined as follows:

spt

This field indicates the number of sectors per track.

tpc

This field indicates the number of tracks per cylinder.

ncyl

This field indicates the number of cylinders.

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.

This function may be called from user or kernel context.
