143 | * Table for parsing mkfs parameters. |
144 | * | |
145 | * Description of the structure members follows: | |
146 | * | |
147 | * name MANDATORY | |
148 | * Name is a single char, e.g., for '-d file', name is 'd'. | |
149 | * | |
150 | * subopts MANDATORY | |
151 | * Subopts is a list of strings naming suboptions. In the example above, | |
152 | * it would contain "file". The last entry of this list has to be NULL. | |
153 | * | |
154 | * subopt_params MANDATORY | |
155 | * This is a list of structs tied with subopts. For each entry in subopts, | |
156 | * a corresponding entry has to be defined: | |
157 | * | |
158 | * subopt_params struct: | |
159 | * index MANDATORY | |
160 | * This number, starting from zero, denotes which item in subopt_params | |
161 | * it is. The index has to be the same as is the order in subopts list, | |
162 | * so we can access the right item both in subopt_param and subopts. | |
163 | * | |
9090e187 DC |
164 | * seen INTERNAL |
165 | * Do not set this flag when definning a subopt. It is used to remeber that | |
166 | * this subopt was already seen, for example for conflicts detection. | |
167 | * | |
27ae3a59 DC |
168 | * str_seen INTERNAL |
169 | * Do not set. It is used internally for respecification, when some options | |
170 | * has to be parsed twice - at first as a string, then later as a number. | |
171 | * | |
627e74fd DC |
172 | * convert OPTIONAL |
173 | * A flag signalling whether the user-given value can use suffixes. | |
174 | * If you want to allow the use of user-friendly values like 13k, 42G, | |
175 | * set it to true. | |
176 | * | |
177 | * is_power_2 OPTIONAL | |
178 | * An optional flag for subopts where the given value has to be a power | |
179 | * of two. | |
180 | * | |
3ec1956a DC |
181 | * conflicts MANDATORY |
182 | * If your subopt is in a conflict with some other option, specify it. | |
183 | * Accepts the .index values of the conflicting subopts and the last | |
184 | * member of this list has to be LAST_CONFLICT. | |
185 | * | |
a9dad670 DC |
186 | * minval, maxval OPTIONAL |
187 | * These options are used for automatic range check and they have to be | |
188 | * always used together in pair. If you don't want to limit the max value, | |
189 | * use something like UINT_MAX. If no value is given, then you must either | |
190 | * supply your own validation, or refuse any value in the 'case | |
191 | * X_SOMETHING' block. If you forget to define the min and max value, but | |
192 | * call a standard function for validating user's value, it will cause an | |
193 | * error message notifying you about this issue. | |
194 | * | |
195 | * (Said in another way, you can't have minval and maxval both equal | |
196 | * to zero. But if one value is different: minval=0 and maxval=1, | |
197 | * then it is OK.) | |
56e4d368 DC |
198 | * |
199 | * defaultval MANDATORY | |
200 | * The value used if user specifies the subopt, but no value. | |
201 | * If the subopt accepts some values (-d file=[1|0]), then this | |
202 | * sets what is used with simple specifying the subopt (-d file). | |
203 | * A special SUBOPT_NEEDS_VAL can be used to require a user-given | |
204 | * value in any case. | |
