Kernel Functions for Driverscsx_Parse_CISTPL_GEOMETRY(9F)


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);

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_geometry_t structure which contains the parsed CISTPL_GEOMETRY tuple information upon return from this function.

DESCRIPTION

 

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.

STRUCTURE MEMBERS

 

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.

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.
