/*
 * Read & Write functions are called as follows:
 * (note: read & write can be NULL if fhe_editmem is set.
 *  if editmem is set & read&write are not NULL, then it is assumed
 *  that mem points to the memory image of what read&write are to
 *  read & write.  (this is usefull for in-memory editing of items
 *  which also are to be read&write))
 *
 *  rc = read (handle, offset, buf, len, &physloc)
 *
 *      rc      - returned, zero sucess.  non-zero error code.
 *	handle	- handle as passed into HexEdit
 *	offset	- byte offset to read/write
 *	buf	- address to read/write data
 *	len	- len to read/write    (probabily a sector, but may be less)
 *	physloc - address to put physcal sector number if known
 *
 *
 *
 *  rc = write (handle, offset, buf, len, physloc)
 *
 *	same as read params, expect 'physloc' is a long passed in and is
 *	whatever was returned to read.
