Implementations

impl OptionalHeader64

pub const MAGIC_PE32PLUS: u16 = 523u16

pub const IMAGE_BASE_OFFSET: usize = 24usize

pub unsafe fn parse( data: *const u8, pe_offset: u32, size: usize, ) -> PeResult<Self>

Parse optional header from memory

Safety

Caller must ensure data + offset points to valid optional header

pub unsafe fn patch_image_base( data: &mut [u8], new_image_base: u64, ) -> PeResult<()>

Patch ImageBase field in a buffer

Safety

Caller must ensure data is valid PE with proper DOS/COFF headers
