An ELF parser library implemented in C.

• Features
• Usage
• Integration

• Efficient Parsing: Written in C for optimal performance and efficiency.
• Versatility: Supports parsing ELF files, including executables and shared libraries.
• Accessible Information: Extracts key information such as section headers, program headers, symbols, and more.
• Integration-Friendly: Easily integrate the library into your projects for seamless ELF file analysis using CMakeLists

1. Include the Library:

    #include "elfo.h"
    
    int fd = open("<bin.elf>", O_RDONLY);
    
    const Elf32_Ehdr eh;
    
    if (fd > 0)
    {
        read_elf_header(fd, &eh);
        
        if(is_elf(&eh))
        {
            assert(eh.e_entry == <0xaddr>);
            assert(is_elf_64(&eh) == true);
        }
        
        close(fd);
    }
    
    <...>

    Elf64_Ehdr eh_64;
    read_elf_header_64(fd, &eh_64);

    Elf64_Shdr *sh_64 = malloc(eh_64.e_shentsize * eh_64.e_shnum);

    read_section_header_table_64(fd, sh_64, eh_64);            

    free(sh_64);

Add the following entry to your CMakeLists.txt file:

add_subdirectory(<clone_path_to_elfo> build/elfo)

Ensure you customize <clone_path_to_elfo> to the appropriate path in your project structure.

To run the tests you need to enter the build/tests folder and then run it inside the ./elfotest folder, you can choose to build or test it or not in CMakeLists by setting BUILD_TESTS
