ctypes is not RPython at all.
But you can use the "lltype" and "rffi" modules.
Your code will certainly use things like:

FUNCTYPE = lltype.Ptr(lltype.FuncType([], rffi.INT))
ptr = rffi.str2charp(machineCode)  # returns a "char*" pointer
my_callback = rffi.cast(FUNCTYPE, ptr)

my_callback() # beware!
