Python ctypes argument errors
- by Patrick Moriarty
Hello. I wrote a test dll in C++ to make sure things work before I start using a more important dll that I need. Basically it takes two doubles and adds them, then returns the result. I've been playing around and with other test functions I've gotten returns to work, I just can't pass an argument due to errors.
My code is:
import ctypes
import string
nDLL = ctypes.WinDLL('test.dll')
func = nDLL['haloshg_add']
func.restype = ctypes.c_double
func.argtypes = (ctypes.c_double,ctypes.c_double)
print(func(5.0,5.0))
It returns the error for the line that called "func":
ValueError: Procedure probably called with too many arguments (8 bytes in excess)
What am I doing wrong? Thanks.
