11 core \- process core file
12 .SH DESCRIPTION
13 .sp
14 .LP
15 The operating system writes out a core file for a process when the process is
16 terminated due to receiving certain signals. A core file is a disk copy of the
17 contents of the process address space at the time the process received the
18 signal, along with additional information about the state of the process. This
19 information can be consumed by a debugger. Core files can also be generated by
20 applying the \fBgcore\fR(1) utility to a running process.
21 .sp
22 .LP
23 Typically, core files are produced following abnormal termination of a process
24 resulting from a bug in the corresponding application. Whatever the cause, the
25 core file itself provides invaluable information to the programmer or support
26 engineer to aid in diagnosing the problem. The core file can be inspected using
27 a debugger such as \fBdbx\fR(1) or \fBmdb\fR(1) or by applying one of the
28 \fBproc\fR(1) tools.
29 .sp
30 .LP
31 The operating system attempts to create up to two core files for each
32 abnormally terminating process, using a global core file name pattern and a
33 per-process core file name pattern. These patterns are expanded to determine

436 and only if the process is a 64-bit process. It contains the ancillary state
437 registers for the \fBLWP.\fR The \fBasrset_t\fR structure is defined in

455 Depending on the \fBcoreadm\fR(1M) settings, the section header of an ELF core
456 file can contain entries for CTF, symbol table, and string table sections. The
457 \fBsh_addr\fR fields are set to the base address of the first mapping of the
458 load object that they came from to. This can be used to match those sections
459 with the corresponding load object.
