9ELFIO是一个只有头文件的C++库，用于读取和生成ELF二进制格式文件。它被用作一个独立的库，它不依赖于任何其他产品或项目。
10它遵循ISO C++，可以在各种架构和编译器上编译。
11
12虽然是用C++编写的，但是该库也提供了一个C语言接口封装器。
13
14完整的库文档可以在【ELFIO-教程和用户手册】（http://elfio.sourceforge.net/elfio.pdf）中找到。

37# 使用说明
38
39（一）加载elf文件
40
411.  调用elfio类的load\(\)接口加载elf文件。
42
43    ELFIO::elfio elfIo;
44    elfIo.load(fileName);
45
46
47（二）获取section名称
48
491.  遍历elf文件的sections。
502.  调用section_impl的get_name\(\)接口获取section名称。
51
52    ELFIO::elfio elfIo;
53    for (const auto &section : elfIo.sections) {
54        if (section->get_name() == "xxx")
55    }
56
57
58（三）获取section数据
59
601.  遍历elf文件的sections。
612.  调用section_impl的get_data\(\)接口获取section数据。
62
63    ELFIO::elfio elfIo;
64    for (const auto &section : elfIo_.sections) {
65        if (section->get_name() == "xxx") {
66            section->get_data();
67        }
68    }
69
70
71（四）获取symbol section
72
731.  遍历elf文件的symbol sections。
742.  调用symbol_section_accessor的get_symbol\(\)接口获取symbol section。
75
76    const symbol_section_accessor symbols(reader, psec);
77    for (unsigned int i = 0; i < symbols.get_symbols_num(); ++i) {
78        std::string name;
79        Elf64_Addr value;
80        Elf_Xword size;
81        unsigned char bind;
82        unsigned char type;
83        Elf_Half section_index;
84        unsigned char other;
85        symbols.get_symbol(i, name, value, size, bind, type, section_index, other);
86    }
87
88
89（五）获取relocation section
90
911.  调用relocation_section_accessor的get_entry\(\)接口获取relocation section。
92
93    Elf64_Addr offset;
94    Elf64_Addr symbolValue;
95    string symbolName;
96    Elf_Word type;
97    Elf_Sxword addend;
98    Elf_Sxword calcValue;
99    relocation_section_accessor reloc(elfIo_, sec);
100    for (uint32_t i = 0; i < sec->get_size() / sec->get_entry_size(); i++) {
101        reloc.get_entry(i, offset, symbolValue, symbolName, type, addend, calcValue);
102    }

8ELFIO is a header-only C++ library intended for reading and generating
9files in the ELF binary format. It is used as a standalone library - it is not
10dependent on any other product or project. Adhering to ISO C++, it compiles on
11a wide variety of architectures and compilers.
12
13While written in C++, the library also provides a C-language interface wrapper.
14
15The full library documentation can be found in *[ELFIO - Tutorial and User Manual](http://elfio.sourceforge.net/elfio.pdf)*.
