Member function with variables parameters

Would anyone have a hint of what's wrong with this


static char szLocalInternetAddress[16];
DWORD dwTest = 0x0002;

g_DmsLog.CreateEntry("Test with DWORD: %ld", dwTest);
g_DmsLog.CreateEntry("System IP: %s ", szLocalInternetAddress);



void CCreateEntry (const char *format, ...)
{
va_list arglist;
char szLine[100];

va_start(arglist, format);
sprintf(szLine, format, arglist);
va_end(arglist);

g_DmsLog.CreateEntry(szLine);

}

The arglist points to nowhere good.

Thanks

re: Member function with variables parameters

Sorry, posted the function in C as I tested if it had something to do with
the code being a class member

void CDmsLog::CreateEntry (const char *format, ...)
{
va_list arglist;
char szLine[100];

EnterCriticalSection(pcsLog);

va_start(arglist, format);
sprintf(szLine, format, arglist);
va_end(arglist);

DoCreateEntry(szLine);

LeaveCriticalSection(pcsLog);
}

re: Member function with variables parameters

Make sure your function is not inline. Some compilers (older GCC) may have
problems with it.

You have been asked several times to stop top-posting. Why do you
continue to do it?

Please read section 5 of the FAQ for posting guidelines:

I thought it was quite a good joke, for a sig.

I have enough to read. This guy has just declared that he has no intention
to keep the common rules of posting here. He has just declared that he does
not give a d...ime. That sig is rather a flame-bait than any kind of good
joke. I may be unable to make one (good joke), but I know when I see one.

I didn't notice that before, or I wouldn't have bothered with my reply.
I'll also be adding him to my killfile now.
