add_log function errors ... (help)

[PhoenixRaider 1]

#include <cstdio>
#include <iostream>

using namespace std;

ofstream ofile;	
ofile.open(GetDirectoryFile("mylog.txt"), ios::app);

void __cdecl add_log (char *fmt, ...)
{
if(ofile != NULL)
{
	if(!fmt) { return; }

	va_list va_alist;
	char logbuf[256] = {0};

	va_start (va_alist, fmt);
	_vsnprintf (logbuf+strlen(logbuf), sizeof(logbuf) - strlen(logbuf), fmt, va_alist);
	va_end (va_alist);

	ofile << logbuf << endl;
}
}

 

I tried using this and it gave me a shit load of errors ...

Then I decided to use it in my code .. to test ..

		CreateThread(NULL, NULL, (LPTHREAD_START_ROUTINE)D3D, NULL, NULL, NULL);
	add_log("Success");

I got more errors ..

1>.\base.cpp(273) : error C3861: 'add_log': identifier not found
