43/* DHCP Option names, formats and codes, from RFC1533.
44
45 Format codes:
46
47 I - IPv4 address
48 R - destination descriptor (RFC3442)
49 6 - IPv6 address
50 l - 32-bit signed integer
51 L - 32-bit unsigned integer
52 s - 16-bit signed integer
53 S - 16-bit unsigned integer
54 b - 8-bit signed integer
55 B - 8-bit unsigned integer
56 t - ASCII text
57 T - Lease Time, 32-bit unsigned integer implying a number of seconds from
58 some event. The special all-ones value means 'infinite'. May either
59 be printed as a decimal, eg, "3600", or as this name, eg, "infinite".
60 f - flag (true or false)
61 A - array of all that precedes (e.g., fIA means array of records of
62 a flag and an IP address)
63 a - array of the preceding character (e.g., fIa means a single flag
64 followed by an array of IP addresses)
65 U - name of an option space (universe)
66 F - implicit flag - the presence of the option indicates that the
67 flag is true.
68 o - the preceding value is optional.
69 E - encapsulation, string or colon-separated hex list (the latter
70 two for parsing). E is followed by a text string containing
71 the name of the option space to encapsulate, followed by a '.'.
72 If the E is immediately followed by '.', the applicable vendor
73 option space is used if one is defined.
74 e - If an encapsulation directive is not the first thing in the string,
75 the option scanner requires an efficient way to find the encapsulation.
76 This is done by placing a 'e' at the beginning of the option. The
77 'e' has no other purpose, and is not required if 'E' is the first
78 thing in the option.
79 X - either an ASCII string or binary data. On output, the string is
80 scanned to see if it's printable ASCII and, if so, output as a
81 quoted string. If not, it's output as colon-separated hex. On
82 input, the option can be specified either as a quoted string or as
83 a colon-separated hex list.
84 N - enumeration. N is followed by a text string containing
85 the name of the set of enumeration values to parse or emit,
86 followed by a '.'. The width of the data is specified in the
87 named enumeration. Named enumerations are tracked in parse.c.
88 d - Domain name (e.g., FOO or FOO.BAR) no quotes,
89 on-wire format is RFC 1035.
90 D - Domain list (e.g., "example.com eng.example.com") quoted,
91 on-wire format is RFC 1035.
92 c - When following a 'D' atom, enables compression pointers.
93 Z - Zero-length option
94 k - Key name, unquoted string (e.g. mykey.com or some-text or abc123)
95 parsed with parse_host_name().
