In an attempt to get the hexadecimal representation of the
machine code of a function. Of course, function pointers
cannot be dereferenced. What do?
Furthermore, I would like to be able to do the same for an
`asm` statement.
The function pointer can be casted to a pointer type. It is worth
saying, however, that it is not trivial to find where the *end*
of a function is. In X86 it's not even trivial to find the end of
an instruction!
If you'd just like the bytes for inspection, you could use a tool
like objdump. For more complicated situations you will need to
use a hack to tell you where the end of a function is.
