| 105 | * XXX - this was introduced in SunOS 4.x to distinguish between |
| 106 | * the old pre-4.x "mmap()", which: |
| 107 | * |
| 108 | * only let you map devices with an "mmap" routine (e.g., |
| 109 | * frame buffers) in; |
| 110 | * |
| 111 | * required you to specify the mapping address; |
| 112 | * |
| 113 | * returned 0 on success and -1 on failure; |
| 114 | * |
| 115 | * memory and which, and the 4.x "mmap()" which: |
| 116 | * |
| 117 | * can map plain files; |
| 118 | * |
| 119 | * can be asked to pick where to map the file; |
| 120 | * |
| 121 | * returns the address where it mapped the file on success |
| 122 | * and -1 on failure. |
| 123 | * |
| 124 | * It's not actually used in source code that calls "mmap()"; the |
| 125 | * "mmap()" routine adds it for you. |
| 126 | * |
| 127 | * It'd be nice to come up with some way of eliminating it from |
| 128 | * the flags, e.g. reporting calls *without* it as "old_mmap()" |
| 129 | * and calls with it as "mmap()". |
