100 | .SH DESCRIPTION | |
101 | This library supports the Athena Service Management System protocol | |
102 | and related operations. The library contains many routines beyond | |
103 | those described in this man page, but they are not intended to be used | |
104 | directly. Instead, they are called by the routines that are described. | |
105 | .TP | |
106 | Protocol functions | |
a4a12338 | 107 | All protocol routines return 0 on success, or a value from |
0a796925 | 108 | .I <sms_et.h> |
109 | on failure. An application should connect, authenticate, perform | |
110 | queries, then disconnect. | |
111 | ||
112 | .I sending_version_no | |
113 | may be set to | |
114 | .B SMS_VERSION_1 | |
115 | or | |
116 | .B SMS_VERSION_2 | |
117 | to determine the version of the protocol that will be used. It | |
118 | currently defaults to | |
119 | .B SMS_VERSION_2. | |
120 | ||
121 | .B sms_connect | |
122 | establishes a connection with the SMS server. The | |
123 | .I server | |
124 | specification is of the form hostname:portname, where the portname can | |
125 | be looked up in | |
126 | .B /etc/services. | |
127 | ||
128 | .B sms_auth | |
129 | authenticates an established connection using Kerberos. | |
130 | .I prog | |
131 | is the name of the program making the connection. The program name | |
132 | and the kerberos principal name will be recorded with any changes made | |
133 | to the database through this connection. | |
134 | ||
135 | .B sms_disconnect | |
136 | severs the connection with the SMS server. | |
137 | ||
138 | .B sms_noop | |
139 | pings the SMS server through a "no operation" request, verifying that | |
140 | the connection is still working. | |
141 | ||
142 | .B sms_access | |
143 | Verifies that the authenticated user has the necessary access to | |
144 | perform the query specified by | |
145 | .I name, argc, | |
146 | and | |
147 | .I argv. | |
148 | ||
149 | .B sms_query | |
150 | performs a query. This query may be a retrieval, append, delete, or | |
151 | update of the database. Query | |
152 | .I name | |
153 | will be executed with the | |
154 | .I argc | |
155 | arguments specified in the string array | |
156 | .I argv. | |
157 | For each return tuple, | |
158 | .I callproc | |
159 | will be called with an | |
160 | .I argc, argv, | |
161 | and the value passed to | |
162 | .B sms_query | |
163 | as | |
164 | .I callarg. | |
165 | ||
166 | .B sms_do_update | |
167 | triggers a DCM update immediately on the SMS server. | |
168 | .TP | |
169 | Data manipulation | |
170 | .B format_filesys_type | |
171 | returns a user-displayable representation of the status bits on an NFS | |
172 | physical partition. | |
173 | .I fs_status | |
174 | is the ascii representation of the integer value of that field. | |
175 | ||
176 | .B parse_filesys_type | |
177 | returns the numeric value of the filesystem type, given a string | |
178 | describing an NFS physical partition allocation type. The returned | |
179 | value is a pointer to a static buffer containing the ascii | |
180 | representation of the integer value. | |
181 | ||
182 | .B canonicalize_hostname | |
183 | attempts to update what is possibly the nickname for a host to its | |
184 | canonical form which is a fully specified, uppercase domain name. | |
185 | If the named host is in the namespace, it calls the nameserver to | |
186 | expand it and return the primary name of the host. Otherwise, it just | |
187 | returns the argument. It assumes that | |
188 | .I host | |
189 | was allocated using | |
190 | .I malloc(), | |
191 | and may be freed or realloc'ed before returning. The returned value | |
192 | will be a malloc'ed value, possibly the same buffer as the argument. | |
193 | ||
194 | .B strsave | |
195 | will malloc some memory and make a copy of | |
196 | .I s. | |
197 | ||
198 | .B strtrim | |
199 | will trim whitespace off of both ends of the string | |
200 | .I s. | |
201 | The returned value will be a pointer into the same buffer | |
202 | .I s | |
203 | pointed to. | |
204 | ||
205 | .B sq_create | |
206 | will create an empty save_queue. | |
207 | .TP | |
208 | Simple Queues | |
209 | .B sq_destroy | |
210 | will free all of the memory contained in the queue structure | |
211 | .I sq. | |
212 | It will not attempt to free the elements. | |
213 | ||
214 | .B sq_get_data | |
215 | will fill in | |
216 | .I data | |
217 | with the next piece of data in the queue. If will return 0 if there | |
218 | is no more data in the queue. | |
219 | ||
220 | .B sq_save_args | |
221 | will make a copy of | |
222 | .I argv, | |
223 | null terminate it so that | |
224 | .I argc | |
225 | is not necessary, and save this value on the end of the queue | |
226 | .I sq. | |
227 | ||
228 | .B sq_save_data | |
229 | saves | |
230 | .I data | |
231 | on the end of the queue | |
232 | .I sq. | |
233 | ||
234 | .B sq_save_unique_data | |
235 | will save | |
236 | .I data | |
237 | on the queue if it does not already appear in the queue. If it is | |
238 | already present, nothing is modified and no errors are returned. | |
239 | .B sq_save_unique_string | |
240 | is like | |
241 | .B sq_save_unique_data, | |
242 | except that it uses strcmp on the elements rather than comparing the | |
243 | addresses directly. | |
244 | .TP | |
245 | Menus | |
246 | The menu package requires that the string | |
247 | .B whoami | |
248 | be defined. It is usually set to argv[0] of the program. | |
249 | ||
250 | .B Start_paging | |
251 | initializes menu package and sets up the screen. | |
252 | ||
253 | .B Stop_paging | |
254 | resets the screen to normal mode. This must be done before the | |
255 | program exits to put the tty back into a sane mode. | |
256 | ||
257 | .B Start_menu | |
258 | starts interpreting menus with | |
259 | .I top_menu, | |
260 | giving the menu package complete control of the screen. | |
261 | .B Start_paging | |
262 | must have been called first. | |
263 | ||
264 | .B Start_no_menu | |
265 | starts interpreting menus, but does not entirely give up control of | |
266 | the screen. The menu package will treat the tty as a printing | |
267 | terminal. | |
268 | ||
269 | .B Cleanup_menu | |
270 | aborts the menu package and returns the tty to sane modes. | |
271 | ||
272 | .B Prompt_input | |
a4a12338 | 273 | will get input from the user, using the dialogue window on the screen. |
0a796925 | 274 | It will first display |
275 | .I prompt, | |
276 | then read up to | |
277 | .I buflen | |
278 | bytes into the buffer | |
279 | .I buf. | |
280 | ||
281 | .B Password_input | |
282 | is like | |
283 | .I Prompt_input, | |
284 | except that the value the user types is not echoed. | |
285 | .B Put_message | |
286 | writes | |
287 | .I msg | |
288 | to the screen, appending a newline at the end. | |
