184 | * The dso__data_* external interface provides following functions: | |
185 | * dso__data_fd | |
186 | * dso__data_close | |

c1f9aa0a JO |
188 | * dso__data_read_offset |
189 | * dso__data_read_addr | |
190 | * | |
191 | * Please refer to the dso.c object code for each function and | |
192 | * arguments documentation. Following text tries to explain the | |
193 | * dso file descriptor caching. | |
194 | * | |
195 | * The dso__data* interface allows caching of opened file descriptors | |
196 | * to speed up the dso data accesses. The idea is to leave the file | |
197 | * descriptor opened ideally for the whole life of the dso object. | |
198 | * | |
199 | * The current usage of the dso__data_* interface is as follows: | |
200 | * | |
201 | * Get DSO's fd: | |
202 | * int fd = dso__data_fd(dso, machine); | |
203 | * USE 'fd' SOMEHOW | |
204 | * | |
205 | * Read DSO's data: | |
206 | * n = dso__data_read_offset(dso_0, &machine, 0, buf, BUFSIZE); | |
207 | * n = dso__data_read_addr(dso_0, &machine, 0, buf, BUFSIZE); | |
208 | * | |
209 | * Eventually close DSO's fd: | |
210 | * dso__data_close(dso); | |
211 | * | |
212 | * It is not necessary to close the DSO object data file. Each time new | |
213 | * DSO data file is opened, the limit (RLIMIT_NOFILE/2) is checked. Once | |
214 | * it is crossed, the oldest opened DSO object is closed. | |
215 | * | |
216 | * The dso__delete function calls close_dso function to ensure the | |
217 | * data file descriptor gets closed/unmapped before the dso object | |
218 | * is freed. | |
219 | * | |
220 | * TODO | |
