43 /* DHCP Option names, formats and codes, from RFC1533.
44
45 Format codes:
46
47 I - IPv4 address
48 6 - IPv6 address
49 l - 32-bit signed integer
50 L - 32-bit unsigned integer
51 s - 16-bit signed integer
52 S - 16-bit unsigned integer
53 b - 8-bit signed integer
54 B - 8-bit unsigned integer
55 t - ASCII text
56 T - Lease Time, 32-bit unsigned integer implying a number of seconds from
57 some event. The special all-ones value means 'infinite'. May either
58 be printed as a decimal, eg, "3600", or as this name, eg, "infinite".
59 f - flag (true or false)
60 A - array of all that precedes (e.g., fIA means array of records of
61 a flag and an IP address)
62 a - array of the preceding character (e.g., fIa means a single flag
63 followed by an array of IP addresses)
64 U - name of an option space (universe)
65 F - implicit flag - the presence of the option indicates that the
66 flag is true.
67 o - the preceding value is optional.
68 E - encapsulation, string or colon-separated hex list (the latter
69 two for parsing). E is followed by a text string containing
70 the name of the option space to encapsulate, followed by a '.'.
71 If the E is immediately followed by '.', the applicable vendor
72 option space is used if one is defined.
73 e - If an encapsulation directive is not the first thing in the string,
74 the option scanner requires an efficient way to find the encapsulation.
75 This is done by placing a 'e' at the beginning of the option. The
76 'e' has no other purpose, and is not required if 'E' is the first
77 thing in the option.
78 X - either an ASCII string or binary data. On output, the string is
79 scanned to see if it's printable ASCII and, if so, output as a
80 quoted string. If not, it's output as colon-separated hex. On
81 input, the option can be specified either as a quoted string or as
82 a colon-separated hex list.
83 N - enumeration. N is followed by a text string containing
84 the name of the set of enumeration values to parse or emit,
85 followed by a '.'. The width of the data is specified in the
86 named enumeration. Named enumerations are tracked in parse.c.
87 d - Domain name (e.g., FOO or FOO.BAR) no quotes,
88 on-wire format is RFC 1035.
89 D - Domain list (e.g., "example.com eng.example.com") quoted,
90 on-wire format is RFC 1035.
91 c - When following a 'D' atom, enables compression pointers.
92 Z - Zero-length option
93 k - Key name, unquoted string (e.g. mykey.com or some-text or abc123)
94 parsed with parse_host_name().
