No.

Here is some code:

class MyClass
{
public:
  // NOTE: Fixed number of params (not varargs)
  int MakeAString( char *fmt, char *str, int i, long l );
}
int
MyClass::MakeAString ( char *fmt, char *str, int i, long l );
{
  char tmpstr[200];

  sprintf( tmpstr, "%s", str ); // Works ok.
  sprintf( tmpstr, "%d", i   ); // Also works.
  sprintf( tmpstr, "%ld", l  ); // also works.
  sprintf( tmpstr, "%s %d", str, i );  // str shows up ok, %d shows bogus val
  sprintf( tmpstr, fmt, str, i );  // who knows.
  return(0);
}

So, it seems that anything after the first param (to a function using varargs)
is lost.

Also, I'm trying to use strftime( outstr, size, fmt, tm ) and the format
(which is a passed arg)  doesn't work.

Actually, I posted here because I am using VC++ 1.50, and didn't want
the c++ forum booting me to here because I'm using that...
I thought it was probably a VC++ related problem.  It should be posted
to both.
