I'm curious why you're declaring your main method as extern(Windows).

How to get normal DLL method name

[Denis Mezhov]

DLL

module dllmain;

import std.c.windows.windows;
import core.sys.windows.dll;
import core.stdc.stdio;

__gshared HINSTANCE g_hInst;

extern (Windows)
BOOL DllMain(HINSTANCE hInstance, ULONG ulReason, LPVOID 
pvReserved)

{
final switch (ulReason)
{
case DLL_PROCESS_ATTACH:
g_hInst = hInstance;
dll_process_attach( hInstance, true );
break;

case DLL_PROCESS_DETACH:
dll_process_detach( hInstance, true );
break;

case DLL_THREAD_ATTACH:
dll_thread_attach( true, true );
break;

case DLL_THREAD_DETACH:
dll_thread_detach( true, true );
break;
}
return true;
}

export void dllprint()
{
printf(hello dll world\n);  
}

In Main

FARPROC fp = GetProcAddress(h, dllmain);  // Not work
if fp is null)
{
   printf(error loading symbol()\n);
}


FARPROC fp = GetProcAddress(h, D7dllmain8dllprintFZv); // It 
work

if fp is null)
{
   printf(error loading symbol()\n);
}

How i set/get normal name in DLL?

Sorry

// Not work
FARPROC fp = GetProcAddress(h, dllprint);
if fp is null)
{
printf(error loading symbol()\n);
}

// It work
FARPROC fp = GetProcAddress(h, D7dllmain8dllprintFZv);

if fp is null)
{
printf(error loading symbol()\n);
}

How about this:

// in dll:

extern(C) void dllprint() { /* ... */ }

// in main:

auto fp = GetProcAddress(h, dllprint);

?

Don't work

Oh, sorry

export extern (C) void dllprint()
{
   printf(hello dll world\n);   
}

It work
