[Pyrex] create win32 dll with multiple export functions

[Mark McMahon]

Hi,

Something like the following should work.
cdef public void testFunc():
	.....

cdef + public = function exported from resulting exe/dll.

Use 'depends' (http://www.dependencywalker.com/) to validate that you do actually have functions exported.

It _MAY_ possibly be necessary to create a .def file to force the exported function to be a specific name (some calling conventions, other stuff?) mangle the names slightly (leading underscores usually).

I know it works - I have done it :)

If you are still stuck after trying the above - let me know and I will see how I can help.

Thanks
  Mark

Subject: [Pyrex] create win32 dll with multiple export functions

Hello,

Could someone please tell me, if it is possible to create classic win32 dll with multiple export functions with Pyrex? From what I have read, I understand that
__declspec(dllexport) directive is declared for the main function only. I need to bind that dll to language called unrealscript, where you could bind win32 dll's. Here is a sample from unrealscript documentation of how thee dll should be written in C.

extern "C"
{
struct FVector
{
float x,y,z;
};

__declspec(dllexport) void CallDLL1(wchar_t* s) { MessageBox(0, s, L"Inside the DLL: CallDLL1", MB_OK); // reverse the out parameter string int len = wcslen(s); for(int i=0; i<len>>1;i++) { wchar_t temp = s[i]; s[i] = s[len-i-1]; s[len-i-1] = temp; } }

__declspec(dllexport) FVector* CallDLL2(float x, float y, float z) { static FVector result; // declared static so that the struct's memory is still valid after the function returns.
result.x = x;
result.y = y;
result.z = z;
return &result;
}

thank you for help.....Jan
