Kernel Functions for Drivers                     ldigetsize(9F)



NAME
     ldigetsize - Retrieve device size

SYNOPSIS
     #include 

     int ldigetsize(ldihandlet lh, uint64t *sizep);


PARAMETERS
     lh        Layered handle.


     sizep     Pointer to the caller's  unsigned  64-bit  integer
               buffer.


DESCRIPTION
     The ldigetsize() function uses the layered  driver  handle
     to  calculate and return a device's size. The device size is
     returned within the caller supplied buffer (*sizep). A valid
     layered   driver   handle   must   be   obtained   via   the
     ldiopenbyname(9F)    interface    prior    to     calling
     ldigetsize().

RETURN VALUES
     The ldigetsize() function returns the following values:

     DISUCES    The device size has been returned within  the
                    caller supplied buffer.


     DIFAILURE    The device size could not be found or  deter-
                    mined.


CONTEXT
     This function may be called from user or kernel context.
