| * frame buffers) in; |
| * |
| * required you to specify the mapping address; |

| * can map plain files; |
| * |
| * can be asked to pick where to map the file; |
| * |
| * returns the address where it mapped the file on success |
| * and -1 on failure. |
| * |
| * It's not actually used in source code that calls "mmap()"; the |
| * "mmap()" routine adds it for you. |
| * |
| * It'd be nice to come up with some way of eliminating it from |
| * the flags, e.g. reporting calls *without* it as "old_mmap()" |
