/*
 * 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

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