/*
 * The dso__data_* external interface provides following functions:
 *   dso__data_fd
 *   dso__data_close
 *   dso__data_size
 *   dso__data_read_offset
 *   dso__data_read_addr
 *
 * Please refer to the dso.c object code for each function and
 * arguments documentation. Following text tries to explain the
 * dso file descriptor caching.
 *
 * The dso__data* interface allows caching of opened file descriptors
 * to speed up the dso data accesses. The idea is to leave the file
 * descriptor opened ideally for the whole life of the dso object.
 *
 * The current usage of the dso__data_* interface is as follows:
 *
 * Get DSO's fd:
 *   int fd = dso__data_fd(dso, machine);
 *   USE 'fd' SOMEHOW
 *
 * Read DSO's data:
 *   n = dso__data_read_offset(dso_0, &machine, 0, buf, BUFSIZE);
 *   n = dso__data_read_addr(dso_0, &machine, 0, buf, BUFSIZE);
 *
 * Eventually close DSO's fd:
 *   dso__data_close(dso);
 *
 * It is not necessary to close the DSO object data file. Each time new
 * DSO data file is opened, the limit (RLIMIT_NOFILE/2) is checked. Once
 * it is crossed, the oldest opened DSO object is closed.
 *
 * The dso__delete function calls close_dso function to ensure the
 * data file descriptor gets closed/unmapped before the dso object
 * is freed.
 *
 * TODO

	241	* The dso__data_* external interface provides following functions:
	242	* dso__data_fd
	243	* dso__data_close
6d363459	244	* dso__data_size
c1f9aa0a JO	245	* dso__data_read_offset
	246	* dso__data_read_addr
	247	*
	248	* Please refer to the dso.c object code for each function and
	249	* arguments documentation. Following text tries to explain the
	250	* dso file descriptor caching.
	251	*
	252	* The dso__data* interface allows caching of opened file descriptors
	253	* to speed up the dso data accesses. The idea is to leave the file
	254	* descriptor opened ideally for the whole life of the dso object.
	255	*
	256	* The current usage of the dso__data_* interface is as follows:
	257	*
	258	* Get DSO's fd:
	259	* int fd = dso__data_fd(dso, machine);
	260	* USE 'fd' SOMEHOW
	261	*
	262	* Read DSO's data:
	263	* n = dso__data_read_offset(dso_0, &machine, 0, buf, BUFSIZE);
	264	* n = dso__data_read_addr(dso_0, &machine, 0, buf, BUFSIZE);
	265	*
	266	* Eventually close DSO's fd:
	267	* dso__data_close(dso);
	268	*
	269	* It is not necessary to close the DSO object data file. Each time new
	270	* DSO data file is opened, the limit (RLIMIT_NOFILE/2) is checked. Once
	271	* it is crossed, the oldest opened DSO object is closed.
	272	*
	273	* The dso__delete function calls close_dso function to ensure the
	274	* data file descriptor gets closed/unmapped before the dso object
	275	* is freed.
	276	*
	277	* TODO
