 CSX_PARSE_CISTPL_DEVICEGEO_A 9F "May 16, 1997"
 NAME
csx_Parse_CISTPL_DEVICEGEO_A - parse the Device Geo A tuple

 SYNOPSIS
#include <sys/pccard.h>



int32_t csx_Parse_CISTPL_DEVICEGEO_A(client_handle_t ch, tuple_t *tp,
 cistpl_devicegeo_t *pt);




 INTERFACE LEVEL
illumos DDI Specific (illumos DDI) 

 PARAMETERS
ch 


Client handle returned from csx_RegisterClient(9F).



tp 


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_devicegeo_t structure which contains the parsed
Device Geo A tuple information upon return from this function.




 DESCRIPTION
This function parses the Device Geo A tuple, CISTPL_DEVICEGEO_A, into a
form usable by PC Card drivers.


The CISTPL_DEVICEGEO_A tuple describes the device geometry of attribute
memory partitions.

 STRUCTURE MEMBERS
The structure members of cistpl_devicegeo_t are:

uint32_t info[CISTPL_DEVICEGEO_MAX_PARTITIONS].bus;
uint32_t info[CISTPL_DEVICEGEO_MAX_PARTITIONS].ebs;
uint32_t info[CISTPL_DEVICEGEO_MAX_PARTITIONS].rbs;
uint32_t info[CISTPL_DEVICEGEO_MAX_PARTITIONS].wbs;
uint32_t info[CISTPL_DEVICEGEO_MAX_PARTITIONS].part;
uint32_t info[CISTPL_DEVICEGEO_MAX_PARTITIONS].hwil;





The fields are defined as follows:
info[CISTPL_DEVICEGEO_MAX_PARTITIONS].bus 


This field indicates the card interface width in bytes for the given partition.



info[CISTPL_DEVICEGEO_MAX_PARTITIONS].ebs 


This field indicates the minimum erase block size for the given partition.



info[CISTPL_DEVICEGEO_MAX_PARTITIONS].rbs 


This field indicates the minimum read block size for the given partition.



info[CISTPL_DEVICEGEO_MAX_PARTITIONS].wbs 


This field indicates the minimum write block size for the given partition.



info[CISTPL_DEVICEGEO_MAX_PARTITIONS].part 


This field indicates the segment partition subdivisions for the given
partition.



info[CISTPL_DEVICEGEO_MAX_PARTITIONS].hwil 


This field indicates the hardware interleave for the given partition.




 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.
