NAME
       ldi_get_size - Retrieve device size

SYNOPSIS
       #include <sys/sunldi.h>

       int ldi_get_size(ldi_handle_t lh, uint64_t *sizep);

PARAMETERS
       lh	       Layered handle.

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

DESCRIPTION
       The  ldi_get_size() 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 ldi_open_by_name(9F)  interface	prior  to  calling
       ldi_get_size().

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

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

       DDI_FAILURE	       The device size could not be found or determined.

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