Python import dll

Question

How would I import a winDLL into python and be able to use all of its functions? It only needs doubles and strings.

Answer 1

c-types NOTE!

Using WinDLL (and wintypes, msvcrt) is windows specific imports and does not always work, even on windows! The reason is that it depends on your python installation. Is it native Windows (or using Cygwin or WSL)?

For ctypes, the more portable and correct way is to use cdll like this:

import sys
import ctypes
from ctypes import cdll, c_ulong

kFile = 'C:\\Windows\\System32\\kernel32.dll'
mFile = 'C:\\Windows\\System32\\msvcrt.dll'

try: 
    k32    = cdll.LoadLibrary(kFile)
    msvcrt = cdll.LoadLibrary(mFile)
except OSError as e:
    print("ERROR: %s" % e)
    sys.exit(1)

# do something...
