LIEF::dsc::Dylib Class Reference

This class represents a library embedded in a dyld shared cache. It mirrors the original dyld_cache_image_info structure. More...

#include <Dylib.hpp>

Classes
struct	extract_opt_t
	This structure is used to tweak the extraction process while calling Dylib::get. These options allow to deoptimize the dylib and get an accurate representation of the origin Mach-O binary. More...
class	Iterator
	Dylib Iterator. More...

Member Function Documentation

address()

uint64_t LIEF::dsc::Dylib::address

(

)

const

In-memory address of the library.

get()

std::unique_ptr< LIEF::MachO::Binary > LIEF::dsc::Dylib::get

(

const extract_opt_t &

opt = extract_opt_t()

)

const

Get a MachO::Binary representation for this Dylib.

One can use this function to write back the Mach-O binary on the disk:

dyld_cache->libraries()[12]->get()->write("liblockdown.dylib");

inode()

uint64_t LIEF::dsc::Dylib::inode

(

)

const

File serial number matching stat.st_ino or 0.

Note that for shared cache targeting iOS, this value can hold a hash of the path (if modtime is set to 0)

modtime()

uint64_t LIEF::dsc::Dylib::modtime

(

)

const

Modification time of the library matching stat.st_mtime, or 0.

padding()

uint64_t LIEF::dsc::Dylib::padding

(

)

const

Padding alignment value (should be 0)

path()

std::string LIEF::dsc::Dylib::path

(

)

const

Original path of the library (e.g. /usr/lib/libcryptex.dylib)
