getting a callback function pointer

[sojahulk]

Hi, i trie to im get a pointer to a dll function to pass it as a callback function pointer to another one. i wrote following dll in visual c++ code\#include <windows.h>

HINSTANCE h = 0;

extern "C" __declspec(dllexport) int myDLLload(LPCWSTR lib)

{

if(h == 0)

{

h = LoadLibrary(lib);

return 0; // ok

}

return 1; // error

}

extern "C" __declspec(dllexport) int myDLLgetprocaddr(const char* proc, int* addr, DWORD* err)

{

if(h != 0)

{

*addr = (int)GetProcAddress(h, proc);

return *addr == 0; // ok

}

*err = GetLastError();

return 1; // error

}

extern "C" __declspec(dllexport) void myDLLFree()

{

FreeLibrary(h);

h = 0;

}

/code

i passed the parameters for the loadlibary (lib) and getproc... (proc) as a c-string, (addr) als int32* but it doesnot work. i am not good in writing dlls at all (fortunately there are a lot of nice people in some forums that help a lot ) and i just dont know why that doesnot work.

anyone has a clue?

thanx
