* 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.
