Convert the handful of manuals that had imaginary names,
give them names that really exist.
This also helps jmc@'s ongoing work on improving NAME sections.

| 181 | .Sh DESCRIPTION | ||
| 182 | UI stands for User Interface, and is general purpose set of routines | ||
| 183 | to prompt the user for text-based information. | ||
| 184 | Through user-written methods (see | ||
| 185 | .Xr ui_create 3 Ns ), | ||
| 186 | prompting can be done in any way imaginable, be it plain text prompting, | ||
| 187 | through dialog boxes or from a cell phone. | ||
| 188 | .Pp | ||
| 189 | All the functions work through a context of the type | ||
| 190 | .Vt UI . | ||
| 191 | This context contains all the information needed to prompt correctly | ||
| 192 | as well as a reference to a | ||
| 193 | .Vt UI_METHOD , | ||
| 194 | which is an ordered vector of functions that carry out the actual | ||
| 195 | prompting. | ||
| 196 | .Pp | ||
| 197 | The first thing to do is to create a | ||
| 198 | .Vt UI | ||
| 199 | with | ||
| 200 | .Fn UI_new | ||
| 201 | or | ||
| 202 | .Fn UI_new_method , | ||
| 203 | then add information to it with the | ||
| 204 | .Fn UI_add_* | ||
| 205 | or | ||
| 206 | .Fn UI_dup_* | ||
| 207 | functions. | ||
| 208 | Also, user-defined random data can be passed down to the underlying | ||
| 209 | method through calls to | ||
| 210 | .Fn UI_add_user_data . | ||
| 211 | The default UI method doesn't care about these data, but other methods | ||
| 212 | might. | ||
| 213 | Finally, use | ||
| 214 | .Fn UI_process | ||
| 215 | to actually perform the prompting and | ||
| 216 | .Fn UI_get0_result | ||
| 217 | to find the result to the prompt. | ||
| 218 | .Pp | ||
| 219 | A | ||
| 220 | .Vt UI | ||
| 221 | can contain more than one prompt, which are performed in the given | ||
| 222 | sequence. | ||
| 223 | Each prompt gets an index number which is returned by the | ||
| 224 | .Fn UI_add_* | ||
| 225 | and | ||
| 226 | .Fn UI_dup_* | ||
| 227 | functions, and has to be used to get the corresponding result with | ||
| 228 | .Fn UI_get0_result . | ||
| 229 | .Pp | ||
| 230 | The functions are as follows: | ||
| 231 | .Pp | ||
| 232 | .Fn UI_new | ||
| 233 | creates a new | ||
| 234 | .Vt UI | ||
| 235 | using the default UI method. | ||
| 236 | When done with this UI, it should be freed using | ||
| 237 | .Fn UI_free . | ||
| 238 | .Pp | ||
| 239 | .Fn UI_new_method | ||
| 240 | creates a new | ||
| 241 | .Vt UI | ||
| 242 | using the given UI method. | ||
| 243 | When done with this UI, it should be freed using | ||
| 244 | .Fn UI_free . | ||
| 245 | .Pp | ||
| 246 | .Fn UI_OpenSSL | ||
| 247 | returns the built-in UI method (note: not the default one, since | ||
| 248 | the default can be changed. | ||
| 249 | See further on). | ||
| 250 | This method is the most machine/OS dependent part of OpenSSL and | ||
| 251 | normally generates the most problems when porting. | ||
| 252 | .Pp | ||
| 253 | .Fn UI_free | ||
| 254 | removes | ||
| 255 | .Fa ui | ||
| 256 | from memory, along with all other pieces of memory that are connected | ||
| 257 | to it, like duplicated input strings, results and others. | ||
| 258 | .Pp | ||
| 259 | .Fn UI_add_input_string | ||
| 260 | and | ||
| 261 | .Fn UI_add_verify_string | ||
| 262 | add a prompt to | ||
| 263 | .Fa ui , | ||
| 264 | as well as flags and a result buffer and the desired minimum and | ||
| 265 | maximum sizes of the result. | ||
| 266 | The given information is used to prompt for information, for example | ||
| 267 | a password, and to verify a password (i.e. having the user enter | ||
| 268 | it twice and check that the same string was entered twice). | ||
| 269 | .Fn UI_add_verify_string | ||
| 270 | takes and extra argument that should be a pointer to the result buffer | ||
| 271 | of the input string that it's supposed to verify, or verification will | ||
| 272 | fail. | ||
| 273 | .Pp | ||
| 274 | .Fn UI_add_input_boolean | ||
| 275 | adds a prompt to | ||
| 276 | .Fa ui | ||
| 277 | that's supposed to be answered in a boolean way, with a single | ||
| 278 | character for yes and a different character for no. | ||
| 279 | A set of characters that can be used to cancel the prompt is given as | ||
| 280 | well. | ||
| 281 | The prompt itself is really divided in two, one part being the | ||
| 282 | descriptive text (given through the | ||
| 283 | .Fa prompt | ||
| 284 | argument) and one describing the possible answers (given through the | ||
| 285 | .Fa action_desc | ||
| 286 | argument). | ||
| 287 | .Pp | ||
| 288 | .Fn UI_add_info_string | ||
| 289 | and | ||
| 290 | .Fn UI_add_error_string | ||
| 291 | add strings that are shown at the same time as the prompt for extra | ||
| 292 | information or to show an error string. | ||
| 293 | The difference between the two is only conceptual. | ||
| 294 | With the builtin method, there's no technical difference between them. | ||
| 295 | Other methods may make a difference between them, however. | ||
| 296 | .Pp | ||
| 297 | The flags currently supported are | ||
| 298 | .Dv UI_INPUT_FLAG_ECHO, | ||
| 299 | which is relevant for | ||
| 300 | .Fn UI_add_input_string | ||
| 301 | and will have the users response be echoed (when prompting for a | ||
| 302 | password, this flag should obviously not be used), and | ||
| 303 | .Dv UI_INPUT_FLAG_DEFAULT_PWD , | ||
| 304 | which means that a default password of some sort will be used | ||
| 305 | (completely depending on the application and the UI method). | ||
| 306 | .Pp | ||
| 307 | .Fn UI_dup_input_string , | ||
| 308 | .Fn UI_dup_verify_string , | ||
| 309 | .Fn UI_dup_input_boolean , | ||
| 310 | .Fn UI_dup_info_string , | ||
| 311 | and | ||
| 312 | .Fn UI_dup_error_string | ||
| 313 | are basically the same as their | ||
| 314 | .Fn UI_add_* | ||
| 315 | counterparts, except that they make their own copies of all strings. | ||
| 316 | .Pp | ||
| 317 | .Fn UI_construct_prompt | ||
| 318 | is a helper function that can be used to create a prompt from two pieces | ||
| 319 | of information: an description and a name. | ||
| 320 | The default constructor (if there is none provided by the method used) | ||
| 321 | creates a string "Enter | ||
| 322 | .Em description | ||
| 323 | for | ||
| 324 | .Em name Ns :". | ||
| 325 | With the description "pass phrase" and the file name "foo.key", that | ||
| 326 | becomes "Enter pass phrase for foo.key:". Other methods may create | ||
| 327 | whatever string and may include encodings that will be processed by the | ||
| 328 | other method functions. | ||
| 329 | .Pp | ||
| 330 | .Fn UI_add_user_data | ||
| 331 | adds a piece of memory for the method to use at any time. | ||
| 332 | The builtin UI method doesn't care about this info. | ||
| 333 | Note that several calls to this function doesn't add data, it replaces | ||
| 334 | the previous blob with the one given as argument. | ||
| 335 | .Pp | ||
| 336 | .Fn UI_get0_user_data | ||
| 337 | retrieves the data that has last been given to the | ||
| 338 | .Fa ui | ||
| 339 | with | ||
| 340 | .Fn UI_add_user_data . | ||
| 341 | .Pp | ||
| 342 | .Fn UI_get0_result | ||
| 343 | returns a pointer to the result buffer associated with the information | ||
| 344 | indexed by | ||
| 345 | .Fa i . | ||
| 346 | .Pp | ||
| 347 | .Fn UI_process | ||
| 348 | goes through the information given so far, does all the printing and | ||
| 349 | prompting and returns. | ||
| 350 | .Pp | ||
| 351 | .Fn UI_ctrl | ||
| 352 | adds extra control for the application author. | ||
| 353 | For now, it understands two commands: | ||
| 354 | .Dv UI_CTRL_PRINT_ERRORS , | ||
| 355 | which makes | ||
| 356 | .Fn UI_process | ||
| 357 | print the OpenSSL error stack as part of processing the | ||
| 358 | .Fa ui , | ||
| 359 | and | ||
| 360 | .Dv UI_CTRL_IS_REDOABLE , | ||
| 361 | which returns a flag saying if the used | ||
| 362 | .Fa ui | ||
| 363 | can be used again or not. | ||
| 364 | .Pp | ||
| 365 | .Fn UI_set_default_method | ||
| 366 | changes the default UI method to the one given. | ||
| 367 | .Pp | ||
| 368 | .Fn UI_get_default_method | ||
| 369 | returns a pointer to the current default UI method. | ||
| 370 | .Pp | ||
| 371 | .Fn UI_get_method | ||
| 372 | returns the UI method associated with a given | ||
| 373 | .Fa ui . | ||
| 374 | .Pp | ||
| 375 | .Fn UI_set_method | ||
| 376 | changes the UI method associated with a given | ||
| 377 | .Fa ui . | ||
