Kernel Functions for Drivers        csxParseCISTPLGEOMETRY(9F)



NAME
     csxParseCISTPLGEOMETRY - parse the Geometry tuple

SYNOPSIS
     #include 



     int32t csxParseCISTPLGEOMETRY(clienthandlet ch, tuplet *tu,
          cistplgeometryt *pt);


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).


     pt    Pointer to a cistplgeometryt  structure  which  con-
           tains  the  parsed  CISTPLGEOMETRY  tuple information
           upon return from this function.


DESCRIPTION
     This function parses the  Geometry  tuple,  CISTPLGEOMETRY,
     into a form usable by PC Card drivers.


     The CISTPLGEOMETRY tuple indicates the geometry of a  disk-
     like device.

STRUCTURE MEMBERS
     The structure members of cistplgeometryt are:

         uint32t     spt;
          uint32t     tpc;
          uint32t     ncyl;



     The fields are defined as follows:

     spt     This field  indicates  the  number  of  sectors  per
             track.
