Usage
Sections (readelf -S executable)
parse sections header table from elf binary and return vector of section_t below
typedef struct {
int section_index = 0;
std::intptr_t section_offset, section_addr;
std::string section_name;
std::string section_type;
int section_size, section_ent_size, section_addr_align;
} section_t;get elf sections using elf-parser
#include <elf-parser.h>
elf_parser::Elf_parser elf_parser(executable_path);
std::vector<elf_parser::section_t> secs = elf_parser.get_sections();see example
Segments (readelf -l executable)
parse program header table from elf binary and return vector of segment_t below
typedef struct {
std::string segment_type, segment_flags;
long segment_offset, segment_virtaddr, segment_physaddr, segment_filesize, segment_memsize;
int segment_align;
} segment_t;get elf segments using elf-parser
#include <elf-parser.h>
elf_parser::Elf_parser elf_parser(executable_path);
std::vector<elf_parser::segment_t> segs = elf_parser.get_segments();see example
Symbols (readelf -s executable)
parse symbols table from elf binary and return vector of symbol_t below
typedef struct {
std::string symbol_index;
std::intptr_t symbol_value;
int symbol_num = 0, symbol_size = 0;
std::string symbol_type, symbol_bind, symbol_visibility, symbol_name, symbol_section;
} symbol_t;get elf symbols using elf-parser
#include <elf-parser.h>
elf_parser::Elf_parser elf_parser(executable_path);
std::vector<elf_parser::symbol_t> syms = elf_parser.get_symbols();see example
Relocations (readelf -r executable)
parse relocations with plt address from elf binary and return vector of relocation_t below
typedef struct {
std::intptr_t relocation_offset, relocation_info, relocation_symbol_value;
std::string relocation_type, relocation_symbol_name, relocation_section_name;
std::intptr_t relocation_plt_address;
} relocation_t;get elf relocations using elf-parser
#include <elf-parser.h>
elf_parser::Elf_parser elf_parser(executable_path);
std::vector<elf_parser::relocation_t> relocs = elf_parser.get_relocations();see example
