linker error

[lodo]

Let suppose I'm writing a library for Win32 applications called 
"mylibrary".
The code of a program, called "UserProgram", that uses this 
library would be like this:

UserProgram.d:
import mylibrary;
import std.c.windows.windows;
int WinMain(HINSTANCE hInst,HINSTANCE hPrevInst,LPSTR cmdLine,int 
cmdShow)
{
     //initialization of mylibrary
     //user code
     //de-initialization of mylibrary
}

What i was trying to do with prova0 and prova00 was calling 
WinMain inside mylibrary, doing initialization and then call a 
user-defined procedure with only the user-code. Then, doing 
de-initialization and returning from WinMain inside the libary. 
In this way, the user have to define only his code. Something 
like this:

mylibrary.d:
public import std.c.windows.windows;
extern(C) UserMain();
int WinMain(HINSTANCE hInst,HINSTANCE hPrevInst,LPSTR cmdLine,int 
cmdShow)
{
     //initialization of mylibrary
     UserMain();
     //de-initialization of mylibrary
}
UserProgram.d:
import mylibrary;
extern(C) void UserMain()
{
     //user code
}

I think this second way is much cleaner for the user and prevent 
him from using mylibrary without correct initialization and 
de-initialization.
I can't use static module initializers for this task because i 
need the parameters of WinMain for the initialization.
P.S.: Sorry for my english, I know I'm not very good in it.
