25This directory contains sample programs that demonstrate how to use libelf.
26Manual pages for libelf routines are located in section 3e: Library Functions.
27
28Each of these sample programs displays, or manipulates information from a ELF
29file.  Each program uses libelf differently.  To learn more about ELF files
30and their format refer to the "Linker & Libraries Guide", which is part of the
31"Software Developer Collection", and the "System V Application Binary
32Interface".
33
34The following source files are provided:
35
36pcom.c		print comment: prints the .comment section of an ELF file.
37		Demonstrates how to examine a file opened with
38		elf_begin(ELF_C_READ)
39
40acom.c		append comment: appends to, or creates a .comment section
41		within an ELF file.  Demonstrates the updating of a file with
42		elf_begin(ELF_C_RDWR)
43
44dcom.c		delete comment: deletes a .comment section from an ELF file.
45		Demonstrates the creation of a ELF file with
46		elf_begin(ELF_C_WRITE)
47
48tpcom.c		threaded print comment:  a threaded version of pcom.c.
49		Demonstrates that libelf is MT-Safe and can be used by a
50		threaded program.
51
52dispsyms.c	print symbols:  scans a ELF file for any symbol tables
53		(SHT_SYMTAB, SHT_DYNSYM, or SHT_SUNW_LDYNSYM) and
54		displays the symbol tables contents.
55
56Makefile	make file to build the above programs.
