Python: Can we convert a ctypes structure to a dictionary?

Question

I have a ctypes structure.

class S1 (ctypes.Structure):
    _fields_ = [
    (\'A\',     ctypes.c_uint16 * 10),
    (\'B\',     ctypes.c_uint32),
    (\'C\',            


        

Answer 1

A little bit more general purpose to handle double arrays, and arrays of structures, and bitfields.

def getdict(struct):
    result = {}
    #print struct
    def get_value(value):
         if (type(value) not in [int, long, float, bool]) and not bool(value):
             # it's a null pointer
             value = None
         elif hasattr(value, "_length_") and hasattr(value, "_type_"):
             # Probably an array
             #print value
             value = get_array(value)
         elif hasattr(value, "_fields_"):
             # Probably another struct
             value = getdict(value)
         return value
    def get_array(array):
        ar = []
        for value in array:
            value = get_value(value)
            ar.append(value)
        return ar
    for f  in struct._fields_:
         field = f[0]
         value = getattr(struct, field)
         # if the type is not a primitive and it evaluates to False ...
         value = get_value(value)
         result[field] = value
    return result
