libdasm is a C-library that tries to provide simple and convenient way to disassemble Intel x86 raw opcode bytes (machine code). It can parse and print out opcodes in AT&T and Intel syntax. The opcodes are based on IA-32 Intel Architecture Software Developer's Manual Volume 2: Instruction Set Reference, order number 243667 , year 2004. Non-Intel instructions are not supported atm (also, non-Intel but Intel-compatible cpu extensions, like AMD 3DNow! are not supported). libdasm should compile with all decent C-compilers (only gcc and MSVC tested). , year 2004.
