I want to access dynamic libraries on different platforms, but I still can not get the function, so do not write it? Where is wrong?

	import std.c.windows.windows;

{
	version(Windows)
    {
        FARPROC proc = GetProcAddress(cast(HMODULE)handle, name.ptr);
        if (proc is null)
        {
			writefln(": can't resolve symbol "~name);
			return null;
        }
        return cast(void*)proc;
    }
	else version(Posix)
    {
        auto cstr = toStringz(symbol);
        return dlsym(handle, cstr);
    }
}

	}
	private void** fptr;
}

template bindFunc(T)
{
	Binder!(T) bindFunc(inout T a)
	{
		Binder!(T) res;
		res.fptr = cast(void**)&a;
		return res;
	}
}

extern (C)
{
	void function() net_tcp_send;	
}

void LoadPlatform(void* lib)
{
	bindFunc(net_tcp_send)("net_tcp_send", lib);
}

int main()
{
	void* hp  = Runtime.loadLibrary("ShuNet.dll".dup);
    if(hp is null)
    {
        writefln("error loading ShuNet.dll");
        return 1;
    }
	writefln("ShuNet.dll is loaded");

	LoadPlatform(hp);
		
	printf("net_tcp_send=>%p", net_tcp_send);

	net_tcp_send(); // this error

	if(!Runtime.unloadLibrary(hp))
    {
		writefln("error freeing ShuNet.dll");
        return 1;
    }
    writefln("End...");

    return 0;
}

runtime.loadlibrary is not yet finished. use dlopen/LoadLibrary instead(forgot about loading D dll's though, its not going to work this way properly(i mean GC/Runtime attaching))

Unfinished? Amount. . .
I am writing with reference to forward and, in theory, is finished.
Call Walter Bright old man!

Unfinished? Amount. . .
I am writing with reference to the http://dlang.org/dll-linux.html and http://dlang.org/dll.html, in theory, is finished. Calls Walter Bright old man! help me!

haha!

Binder!(T) bindFunc(inout T a)

is inout error!
