198 * The dso__data_* external interface provides following functions:
202 * dso__data_read_offset
203 * dso__data_read_addr
205 * Please refer to the dso.c object code for each function and
206 * arguments documentation. Following text tries to explain the
207 * dso file descriptor caching.
209 * The dso__data* interface allows caching of opened file descriptors
210 * to speed up the dso data accesses. The idea is to leave the file
211 * descriptor opened ideally for the whole life of the dso object.
213 * The current usage of the dso__data_* interface is as follows:
216 * int fd = dso__data_fd(dso, machine);
220 * n = dso__data_read_offset(dso_0, &machine, 0, buf, BUFSIZE);
221 * n = dso__data_read_addr(dso_0, &machine, 0, buf, BUFSIZE);
223 * Eventually close DSO's fd:
224 * dso__data_close(dso);
226 * It is not necessary to close the DSO object data file. Each time new
227 * DSO data file is opened, the limit (RLIMIT_NOFILE/2) is checked. Once
228 * it is crossed, the oldest opened DSO object is closed.
230 * The dso__delete function calls close_dso function to ensure the
231 * data file descriptor gets closed/unmapped before the dso object
