The special all-ones value means 'infinite'. May either 63 be printed as a decimal, eg, "3600", or as this name, eg, "infinite". 64 f - flag (true or false) 65 A - array of all that precedes (e.g., fIA means array of records of 66 a flag and an IP address) 67 a - array of the preceding character (e.g., fIa means a single flag 68 followed by an array of IP addresses) 69 U - name of an option space (universe) 70 F - implicit flag - the presence of the option indicates that the 71 flag is true. 72 o - the preceding value is optional. 73 E - encapsulation, string or colon-separated hex list (the latter 74 two for parsing). E is followed by a text string containing 75 the name of the option space to encapsulate, followed by a '.'. 76 If the E is immediately followed by '.', the applicable vendor 77 option space is used if one is defined. 78 e - If an encapsulation directive is not the first thing in the string, 79 the option scanner requires an efficient way to find the encapsulation. 80 This is done by placing a 'e' at the beginning of the option. The 81 'e' has no other purpose, and is not required if 'E' is the first 82 thing in the option. 83 X - either an ASCII string or binary data. On output, the string is 84 scanned to see if it's printable ASCII and, if so, output as a 85 quoted string. If not, it's output as colon-separated hex. On 86 input, the option can be specified either as a quoted string or as 87 a colon-separated hex list. 88 N - enumeration. N is followed by a text string containing 89 the name of the set of enumeration values to parse or emit, 90 followed by a '.'. The width of the data is specified in the 91 named enumeration. Named enumerations are tracked in parse.c. 92 d - Domain name (e.g., FOO or FOO.BAR) no quotes, 93 on-wire format is RFC 1035. 94 D - Domain list (e.g., "example.com eng.example.com") quoted, 95 on-wire format is RFC 1035. 96 c - When following a 'D' atom, enables compression pointers. 97 Z - Zero-length option 98 k - Key name, unquoted string (e.g. mykey.com or some-text or abc123) 99 parsed with parse_host_name(). 100 */ 101 102 struct universe dhcp_universe; 103 static struct option dhcp_options[] = { 104 { "subnet-mask", "I", &dhcp_universe, 1, 1 }, 105 { "time-offset", "l",
