79 * `1 octet tag | key', where the tag is one of the _PW_KEY* values |
|
80 * listed below. These values happen to be ASCII digits. Starting |
|
81 * with FreeBSD 5.1, the tag is now still a single octet, but the |
|
82 * upper 4 bits are interpreted as a version. Pre-FreeBSD 5.1 format |
|
83 * entries are version `3' -- this conveniently results in the same |
|
84 * key values as before. The new, architecture-independent entries |
|
85 * are version `4'. |
|
86 * As it happens, some applications read the database directly. |
|
87 * (Bad app, no cookie!) Thus, we leave the _PW_KEY* symbols at their |
|
88 * old pre-FreeBSD 5.1 values so these apps still work. Consequently |
|
89 * we have to muck around a bit more to get the correct, versioned |
|
90 * tag, and that is what the _PW_VERSIONED macro is about. |
