Hi,
I'v made a c-module to simplify embedding/extending Python without the need
of a MS-C compiler (MingW is good enough) and without the hassle of
packing/unpacking/ref-counting/thread-state when communicating with python.
Using my c-module, your dll should look something like:
-------------------------------------------------------
#include "PyLib.h"
typedef enum _Status
{
STATUS_SUCCESS = 0x00000000,
STATUS_FAILED = 0x00000001
}Status;
typedef struct _ApiVersionInfo
{
DWORD dwMajor;
DWORD dwMinor;
DWORD dwDetailed
}ApiVersionInfo;
static initialized = 0;
static Initialize()
{
if (!initialized) {
PyLib_Initialize(NULL, 0, NULL);
PyLib_Import("MyDll", r"C:\Dir\Containing\MyDll");
initialized = 1;
}
}
Status GetApiVersion(ApiVersionInfo *pstVersion)
{
Initialize();
if (PyLib_Call("MyDll.GetApiVersion", "iii()",
&(pstVersion->dwMajor),
&(pstVersion->dwMinor), &(pstVersion->dwDetailed)))
return STATUS_SUCCESS;
else
return STATUS_FAILED;
}
-------------------------------------------------------
and you must create a file "MyDll.py" with something like:
-------------------------------------------------------
def GetApiVersion():
return 1, 1, 0
-------------------------------------------------------
Since the documentation is not ready I've not yet released this to the
general python community.
If you are interested I can send you the code.
