Module goblin::mach::header [−][src]
A header contains minimal architecture information, the binary kind, the number of load commands, as well as an endianness hint
Structs
| Header | Generic sized header |
| Header32 | A 32-bit Mach-o header |
| Header64 | A 64-bit Mach-o header |
Constants
| MH_ALLMODSBOUND | indicates that this binary binds to all two-level namespace modules of its dependent libraries. Only used when MH_PREBINDABLE and MH_TWOLEVEL are both set. |
| MH_ALLOW_STACK_EXECUTION | When this bit is set, all stacks in the task will be given stack execution privilege. Only used in MH_EXECUTE filetypes. |
| MH_APP_EXTENSION_SAFE | The code was linked for use in an application extension. |
| MH_BINDATLOAD | the object file’s undefined references are bound by the dynamic linker when loaded. |
| MH_BINDS_TO_WEAK | the final linked image uses weak symbols |
| MH_BUNDLE | dynamically bound bundle file |
| MH_CANONICAL | the binary has been canonicalized via the unprebind operation |
| MH_CIGAM | |
| MH_CIGAM_64 | |
| MH_CORE | core file |
| MH_DEAD_STRIPPABLE_DYLIB | Only for use on dylibs. When linking against a dylib that has this bit set, the static linker will automatically not create a LC_LOAD_DYLIB load command to the dylib if no symbols are being referenced from the dylib. |
| MH_DSYM | companion file with only debug sections |
| MH_DYLDLINK | the object file is input for the dynamic linker and can’t be staticly link edited again |
| MH_DYLIB | dynamically bound shared library |
| MH_DYLIB_STUB | shared library stub for static linking only, no section contents |
| MH_DYLINKER | dynamic link editor |
| MH_EXECUTE | demand paged executable file |
| MH_FORCE_FLAT | the executable is forcing all images to use flat name space bindings |
| MH_FVMLIB | fixed VM shared library file |
| MH_HAS_TLV_DESCRIPTORS | Contains a section of type S_THREAD_LOCAL_VARIABLES |
| MH_INCRLINK | the object file is the output of an incremental link against a base file and can’t be link edited again |
| MH_KEXT_BUNDLE | x86_64 kexts |
| MH_LAZY_INIT | the shared library init routine is to be run lazily via catching memory faults to its writeable segments (obsolete) |
| MH_MAGIC | Mach Header magic constant |
| MH_MAGIC_64 | Mach Header magic constant for 64-bit |
| MH_NOFIXPREBINDING | do not have dyld notify the prebinding agent about this executable |
| MH_NOMULTIDEFS | this umbrella guarantees no multiple defintions of symbols in its sub-images so the two-level namespace hints can always be used. |
| MH_NOUNDEFS | the object file has no undefined references |
| MH_NO_HEAP_EXECUTION | When this bit is set, the OS will run the main executable with a non-executable heap even on platforms (e.g. i386) that don’t require it. Only used in MH_EXECUTE filetypes. |
| MH_NO_REEXPORTED_DYLIBS | When this bit is set on a dylib, the static linker does not need to examine dependent dylibs to see if any are re-exported |
| MH_OBJECT | relocatable object file |
| MH_PIE | When this bit is set, the OS will load the main executable at a random address. Only used in MH_EXECUTE filetypes. |
| MH_PREBINDABLE | the binary is not prebound but can have its prebinding redone. only used when MH_PREBOUND is not set. |
| MH_PREBOUND | the file has its dynamic undefined references prebound. |
| MH_PRELOAD | preloaded executable file |
| MH_ROOT_SAFE | When this bit is set, the binary declares it is safe for use in processes with uid zero |
| MH_SETUID_SAFE | When this bit is set, the binary declares it is safe for use in processes when issetugid() is true |
| MH_SPLIT_SEGS | the file has its read-only and read-write segments split |
| MH_SUBSECTIONS_VIA_SYMBOLS | safe to divide up the sections into sub-sections via symbols for dead code stripping |
| MH_TWOLEVEL | the image is using two-level name space bindings |
| MH_WEAK_DEFINES | the final linked image contains external weak symbols |
| SIZEOF_HEADER_32 | |
| SIZEOF_HEADER_64 |
