153 * The dso__data_* external interface provides following functions:
156 * dso__data_read_offset
157 * dso__data_read_addr
159 * Please refer to the dso.c object code for each function and
160 * arguments documentation. Following text tries to explain the
161 * dso file descriptor caching.
163 * The dso__data* interface allows caching of opened file descriptors
164 * to speed up the dso data accesses. The idea is to leave the file
165 * descriptor opened ideally for the whole life of the dso object.
167 * The current usage of the dso__data_* interface is as follows:
170 * int fd = dso__data_fd(dso, machine);
174 * n = dso__data_read_offset(dso_0, &machine, 0, buf, BUFSIZE);
175 * n = dso__data_read_addr(dso_0, &machine, 0, buf, BUFSIZE);
177 * Eventually close DSO's fd:
178 * dso__data_close(dso);
180 * It is not necessary to close the DSO object data file. Each time new
181 * DSO data file is opened, the limit (RLIMIT_NOFILE/2) is checked. Once
182 * it is crossed, the oldest opened DSO object is closed.
184 * The dso__delete function calls close_dso function to ensure the
185 * data file descriptor gets closed/unmapped before the dso object
