77 * SA_RESTART flag to get restarting signals (which were the default long ago)
78 * SA_NOCLDSTOP flag to turn off SIGCHLD when children stop.
79 * SA_RESETHAND clears the handler when the signal is delivered.
80 * SA_NOCLDWAIT flag on SIGCHLD to inhibit zombies.
81 * SA_NODEFER prevents the current signal from being masked in the handler.
82 *
83 * SA_ONESHOT and SA_NOMASK are the historical Linux names for the Single
84 * Unix names RESETHAND and NODEFER respectively.

17/* Core file format: The core file is written in such a way that gdb
18 * can understand it and provide useful information to the user (under
19 * linux we use the 'trad-core' bfd). There are quite a number of
20 * obstacles to being able to view the contents of the floating point
21 * registers, and until these are solved you will not be able to view
22 * the contents of them. Actually, you can read in the core file and
23 * look at the contents of the user struct to find out what the
24 * floating point registers contain.
25 *
26 * The actual file contents are as follows:
27 * UPAGE:
28 * 1 page consisting of a user struct that tells gdb what is present
29 * in the file. Directly after this is a copy of the task_struct,
30 * which is currently not used by gdb, but it may come in useful at
31 * some point. All of the registers are stored as part of the
32 * upage. The upage should always be only one page.
33 *
34 * DATA:
35 * The data area is stored. We use current->end_text to
36 * current->brk to pick up all of the user variables, plus any
37 * memory that may have been malloced. No attempt is made to
38 * determine if a page is demand-zero or if a page is totally
39 * unused, we just cover the entire range. All of the addresses are
40 * rounded in such a way that an integral number of pages is
41 * written.
42 *
43 * STACK:
44 * We need the stack information in order to get a meaningful
45 * backtrace. We need to write the data from (esp) to
46 * current->start_stack, so we round each of these off in order to
47 * be able to write an integer number of pages. The minimum core
48 * file size is 3 pages, or 12288 bytes.
49 */

51/* When the kernel dumps core, it starts by dumping the user struct -

53 * are within the file, and what virtual addresses to use.
