/* Map addresses starting near ADDR and extending for LEN bytes.  From
Packit 6c4009
   OFFSET into the file FD describes according to PROT and FLAGS.  If ADDR
Packit 6c4009
   is nonzero, it is the desired mapping address.  If the MAP_FIXED bit is
Packit 6c4009
   set in FLAGS, the mapping will be at ADDR exactly (which must be
Packit 6c4009
   page-aligned); otherwise the system chooses a convenient nearby address.
Packit 6c4009
   The return value is the actual mapping address chosen or MAP_FAILED
Packit 6c4009
   for errors (in which case `errno' is set).  A successful `mmap' call
Packit 6c4009
   deallocates any previous mapping for the affected region.  */
