Struct goblin::elf::section_header::section_header32::SectionHeader

#[repr(C)]
pub struct SectionHeader {
    pub sh_name: u32,
    pub sh_type: u32,
    pub sh_flags: u32,

Section Headers are typically used by humans and static linkers for additional information or how to relocate the object

NOTE section headers are strippable from a binary without any loss of portability/executability; do not rely on them being there!

sh_link: u32

Link to another section

sh_info: u32
