ddn.elf

ddn.elf - High-Level ELF Library Package

This module provides a high-level, user-friendly API for working with ELF files. It re-exports commonly used types and provides convenience functions for common tasks.

Example: 

// Read an ELF file
auto file = openElf("my_program.elf");

// Get file information
auto info = getElfInfo("my_program.elf");
writeln("Class: ", info.class_);
writeln("Machine: ", info.machine);

// List symbols
foreach (sym; listSymbols(file))
{
   writeln(sym.name, " @ ", sym.address);
}

Types 3

structElfInfo

Summary information about an ELF file.

Fields
ElfClass class_ELF class (32-bit or 64-bit)
ElfData endianEndianness (little or big)
