55 | * Table for parsing mkfs parameters. |
56 | * | |
57 | * Description of the structure members follows: | |
58 | * | |
59 | * name MANDATORY | |
60 | * Name is a single char, e.g., for '-d file', name is 'd'. | |
61 | * | |
62 | * subopts MANDATORY | |
63 | * Subopts is a list of strings naming suboptions. In the example above, | |
64 | * it would contain "file". The last entry of this list has to be NULL. | |
65 | * | |
66 | * subopt_params MANDATORY | |
67 | * This is a list of structs tied with subopts. For each entry in subopts, | |
68 | * a corresponding entry has to be defined: | |
69 | * | |
70 | * subopt_params struct: | |
71 | * index MANDATORY | |
72 | * This number, starting from zero, denotes which item in subopt_params | |
73 | * it is. The index has to be the same as is the order in subopts list, | |
74 | * so we can access the right item both in subopt_param and subopts. | |
75 | * | |
9090e187 DC |
76 | * seen INTERNAL |
77 | * Do not set this flag when definning a subopt. It is used to remeber that | |
78 | * this subopt was already seen, for example for conflicts detection. | |
79 | * | |
27ae3a59 DC |
80 | * str_seen INTERNAL |
81 | * Do not set. It is used internally for respecification, when some options | |
82 | * has to be parsed twice - at first as a string, then later as a number. | |
83 | * | |
627e74fd DC |
84 | * convert OPTIONAL |
85 | * A flag signalling whether the user-given value can use suffixes. | |
86 | * If you want to allow the use of user-friendly values like 13k, 42G, | |
87 | * set it to true. | |
88 | * | |
89 | * is_power_2 OPTIONAL | |
90 | * An optional flag for subopts where the given value has to be a power | |
91 | * of two. | |
92 | * | |
3ec1956a DC |
93 | * conflicts MANDATORY |
94 | * If your subopt is in a conflict with some other option, specify it. | |
95 | * Accepts the .index values of the conflicting subopts and the last | |
96 | * member of this list has to be LAST_CONFLICT. | |
97 | * | |
a9dad670 DC |
98 | * minval, maxval OPTIONAL |
99 | * These options are used for automatic range check and they have to be | |
100 | * always used together in pair. If you don't want to limit the max value, | |
101 | * use something like UINT_MAX. If no value is given, then you must either | |
102 | * supply your own validation, or refuse any value in the 'case | |
103 | * X_SOMETHING' block. If you forget to define the min and max value, but | |
104 | * call a standard function for validating user's value, it will cause an | |
105 | * error message notifying you about this issue. | |
106 | * | |
107 | * (Said in another way, you can't have minval and maxval both equal | |
108 | * to zero. But if one value is different: minval=0 and maxval=1, | |
109 | * then it is OK.) | |
56e4d368 DC |
110 | * |
111 | * defaultval MANDATORY | |
112 | * The value used if user specifies the subopt, but no value. | |
113 | * If the subopt accepts some values (-d file=[1|0]), then this | |
114 | * sets what is used with simple specifying the subopt (-d file). | |
115 | * A special SUBOPT_NEEDS_VAL can be used to require a user-given | |
116 | * value in any case. | |
