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:

        break;

        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()

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