hooking send() and call the original

i detoured the send() with success, and in my detoured function i want to call the ORIGINAL function !

How to do it if the original itself get hooked, its will go into a loop !

Code:

void *DetourFunc(BYTE *src, const BYTE *dst, const int len)
{
	BYTE *jmp = (BYTE*)malloc(len+5);
	DWORD dwback;

	VirtualProtect(src, len, PAGE_READWRITE, &dwback);

	memcpy(jmp, src, len);	jmp += len;
	
	jmp[0] = 0xE9;
	*(DWORD*)(jmp+1) = (DWORD)(src+len - jmp) - 5;

	src[0] = 0xE9;
	*(DWORD*)(src+1) = (DWORD)(dst - src) - 5;

	VirtualProtect(src, len, dwback, &dwback);

	return (jmp-len);
}

int WINAPI mysend(SOCKET s,	const char* buf, int len, int flags)
{
	MessageBox(NULL, buf, "I caught a packet :) !!!", NULL);
	send(s, buf, len, flags);
	return 1;
}

BOOL APIENTRY DllMain( HMODULE hModule,
                       DWORD  ul_reason_for_call,
                       LPVOID lpReserved
					 )
{
	DisableThreadLibraryCalls(hModule);

	hMod = LoadLibrary("ws2_32.dll");
		
	DetourFunc((BYTE*)GetProcAddress(hMod, "send"), (BYTE*)mysend,2);

    return TRUE;
}

im new here, i hope that members can help me.
thank you
