 CSX_PARSE_CISTPL_FORMAT 9F "Jan 24, 1997"
 NAME
csx_Parse_CISTPL_FORMAT - parse the Data Recording Format tuple

 SYNOPSIS


#include <sys/pccard.h>



int32_t csx_Parse_CISTPL_FORMAT(client_handle_t ch, tuple_t *tu,
 cistpl_format_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_format_t structure which contains the parsed
CISTPL_FORMAT tuple information upon return from this function.




 DESCRIPTION

This function parses the Data Recording Format tuple, CISTPL_FORMAT, into
a form usable by PC Card drivers.


The CISTPL_FORMAT tuple indicates the data recording format for a device
partition.

 STRUCTURE MEMBERS

The structure members of cistpl_format_t are:

uint32_t type;
uint32_t edc_length;
uint32_t edc_type;
uint32_t offset;
uint32_t nbytes;
uint32_t dev.disk.bksize;
uint32_t dev.disk.nblocks;
uint32_t dev.disk.edcloc;
uint32_t dev.mem.flags;
uint32_t dev.mem.reserved;
caddr_t dev.mem.address;
uint32_t dev.mem.edcloc;





The fields are defined as follows:
type


This field indicates the type of device:
TPLFMTTYPE_DISK


disk-like device



TPLFMTTYPE_MEM


memory-like device



TPLFMTTYPE_VS


vendor-specific device






edc_length


This field indicates the error detection code length.



edc_type


This field indicates the error detection code type.



offset


This field indicates the offset of the first byte of data in this partition.



nbytes


This field indicates the number of bytes of data in this partition



dev.disk.bksize


This field indicates the block size, for disk devices.



dev.disk.nblocks


This field indicates the number of blocks, for disk devices.



dev.disk.edcloc


This field indicates the location of the error detection code, for disk
devices.



dev.mem.flags


This field provides flags, for memory devices. Valid flags are:
TPLFMTFLAGS_ADDR


address is valid



TPLFMTFLAGS_AUTO


automatically map memory region






dev.mem.reserved


This field is reserved.



dev.mem.address


This field indicates the physical address, for memory devices.



dev.mem.edcloc


This field indicates the location of the error detection code, for memory
devices.




 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.
