Kernel Functions for Drivers       csxParseCISTPLBYTEORDER(9F)



NAME
     csxParseCISTPLBYTEORDER - parse the Byte Order tuple

SYNOPSIS
     #include 



     int32t csxParseCISTPLBYTEORDER(clienthandlet ch, tuplet *tu,
          cistplbyteordert *cbo);


INTERFACE LEVEL
     Solaris DI Specific (Solaris DI)

PARAMETERS
     ch      Client handle returned from csxRegisterClient(9F).


     tu      Pointer  to  a  tuplet  structure  (see  tuple(9S))
             returned  by  a  call  to  csxGetFirstTuple(9F)  or
             csxGetNextTuple(9F).


     cbo     Pointer to a cistplbyteordert structure which con-
             tains  the parsed CISTPLBYTEORDER tuple information
             upon return from this function.


DESCRIPTION
     This function parses the Byte Order tuple, CISTPLBYTEORDER,
     into a form usable by PC Card drivers.


     The CISTPLBYTEORDER tuple shall only appear in a  partition
     tuple  set  for  a  memory-like  partition. It specifies two
     parameters: the order for multi-byte data, and the order  in
     which bytes map into words for 16-bit cards.

STRUCTURE MEMBERS
     The structure members of cistplbyteordert are:

       uint32t     order;     /* byte order code */
       uint32t     map;       /* byte mapping code */



     The fields are defined as follows:

     order     This field specifies the byte order for multi-byte
               numeric data.

     map       This field specifies the byte mapping  for  16-bit
