I have created a DLL with the following function exported in it
int myFunction(char *id, char *name);
This is a bit beyond beginner python, I suspect you will
get a better response if you ask on the ctypes mailling
list/forum.
Below is the python code to load the dll and call myFunction
from ctypes import *
# Load DLL into memory
mydll= windll.LoadLibrary("my.dll")
id = create_string_buffer("030725002")
name = create_string_buffer("mammar")
print mydll.myFunction(id, name)
Program: C:\Python27\pythonw.exe
file: fread.c
line: 93
Expression: (buffer != NULL)
Looks like a problem in the C code but I don't know if thats
the C in Python or the C in your DLL. I suspect we would need to see
the C in the DLL function.
You could add some print statements to find out where the
error arises...
