Struct object::macho::DyldCacheHeader

#[repr(C)]
pub struct DyldCacheHeader<E: Endian> {
    pub magic: [u8; 16],
    pub mapping_offset: U32<E>,
    pub mapping_count: U32<E>,
    pub images_offset: U32<E>,
    pub images_count: U32<E>,
    pub dyld_base_address: U64<E>,
}

The dyld cache header, containing only the fields which are present in all versions of dyld caches (dyld-95.3 and up). Many more fields exist in later dyld versions, but we currently do not need to parse those. Corresponds to struct dyld_cache_header from dyld_cache_format.h.

Fields

magic: [u8; 16]

e.g. “dyld_v0 i386”

mapping_offset: U32<E>

file offset to first dyld_cache_mapping_info

mapping_count: U32<E>

number of dyld_cache_mapping_info entries

images_offset: U32<E>

file offset to first dyld_cache_image_info

images_count: U32<E>

number of dyld_cache_image_info entries

dyld_base_address: U64<E>

base address of dyld when cache was built

Implementations

impl<E: Endian> DyldCacheHeader<E>

pub fn parse<'data, R: ReadRef<'data>>(data: R) -> Result<&'data Self>

Read the dyld cache header.

pub fn parse_magic(&self) -> Result<(Architecture, E)>

Returns (arch, endian) based on the magic string.

pub fn mappings<'data, R: ReadRef<'data>>(
    &self,
    endian: E,
    data: R
) -> Result<&'data [DyldCacheMappingInfo<E>]>

Return the mapping information table.

pub fn images<'data, R: ReadRef<'data>>(
    &self,
    endian: E,
    data: R
) -> Result<&'data [DyldCacheImageInfo<E>]>

Return the image information table.
