109 * XXX - this was introduced in SunOS 4.x to distinguish between
110 * the old pre-4.x "mmap()", which:
112 * only let you map devices with an "mmap" routine (e.g.,
115 * required you to specify the mapping address;
117 * returned 0 on success and -1 on failure;
119 * memory and which, and the 4.x "mmap()" which:
121 * can map plain files;
123 * can be asked to pick where to map the file;
125 * returns the address where it mapped the file on success
128 * It's not actually used in source code that calls "mmap()"; the
129 * "mmap()" routine adds it for you.
131 * It'd be nice to come up with some way of eliminating it from
132 * the flags, e.g. reporting calls *without* it as "old_mmap()"
133 * and calls with it as "mmap()".
