Expand description

Represents the ELF file header.

This structure contains metadata about the ELF file, such as its type, architecture, entry point, and various offsets for program and section headers.

Fields§

§magic: [u8; 4]

The ELF magic number (0x7F followed by ELF in ASCII).

§class: u8

Indicates 32-bit or 64-bit format.

§data: u8

Specifies little-endian or big-endian encoding.

§version: u8

ELF version (set to 1 for the original and current version).

§abi: u8

Identifies the target operating system ABI.

§abi_version: u8

Further specifies the ABI version.

§pad: [u8; 7]

Unused padding bytes (must be zero).

§e_type: u16

Object file type (e.g., executable, shared object, relocatable).

§e_machine: u16

Target instruction set architecture.

§e_version: u32

ELF version (should be 1).

§e_entry: u64

Memory address of the entry point where execution starts.

§e_phoff: u64

Offset of the program header table in bytes.

§e_shoff: u64

Offset of the section header table in bytes.

§e_flags: u32

Processor-specific flags.

§e_ehsize: u16

Size of this header in bytes.

§e_phentsize: u16

Size of a program header table entry in bytes.

§e_phnum: u16

Number of entries in the program header table.

§e_shentsize: u16

Size of a section header table entry in bytes.

§e_shnum: u16

Number of entries in the section header table.

§e_shstrndx: u16

Index of the section header table entry that contains section names.
