C macro for ellipsis(...)

[klee777]

Hi I'd like to write a macro for the function with a variable argument, for example

#define PrivateLog(szFormat,...) \
          PublicLogWrite(_TODAY_,szFormat,...)
// where _TODAY_ is a static string containing e.g. "May 23, 2007"
 
void PublicLogWrite( char *szToday, char *szFmt, ... )
{
    va_list arglist;
    va_start( arglist, szFmt );
    // ... e.g. vsprintf()
    va_end( arglist );
    // ... e.g. fprintf()
}

so the caller should look like,
PrivateLog( "Error:%s ReturnCode=%d\n", szErrorMessage, nError );
PrivateLog( "Info:%s Len=%d #Lines=%d\n", szInfoMessage, nLen, nNumLines );

But those 2 lines generates the compilation errors:
error C2059: syntax error : '...'

Anyone knows how to resolve this?
TIA.

See here. If your compiler predates C9x standard, it will not work.
