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.
