11 * XXX - this was introduced in SunOS 4.x to distinguish between
12 * the old pre-4.x "mmap()", which:
14 * only let you map devices with an "mmap" routine (e.g.,
17 * required you to specify the mapping address;
19 * returned 0 on success and -1 on failure;
21 * memory and which, and the 4.x "mmap()" which:
23 * can map plain files;
25 * can be asked to pick where to map the file;
27 * returns the address where it mapped the file on success
30 * It's not actually used in source code that calls "mmap()"; the
31 * "mmap()" routine adds it for you.
33 * It'd be nice to come up with some way of eliminating it from
34 * the flags, e.g. reporting calls *without* it as "old_mmap()"
35 * and calls with it as "mmap()".
