+   is nonzero, it is the desired mapping address.  If the MAP_FIXED bit is
+   set in FLAGS, the mapping will be at ADDR exactly (which must be
+   page-aligned); otherwise the system chooses a convenient nearby address.

+   for errors (in which case `errno' is set).  A successful `mmap' call
+   deallocates any previous mapping for the affected region.  */
