"""Disassemble instructions at an address of an ELF/PE/Mach-O binary.
|
|
|
|
Uses LIEF's extended disassembly API to iterate over the instructions
|
|
located at the given virtual address of the binary.
|
|
|
|
Note: only available with the extended version of LIEF.
|
|
|
|
Example:
|
|
|
|
$ python disassembler.py /bin/ls 0x4000
