Good reason (=.

I looked into Objective-C, but I didn't really buy why you'd want to use
Objective-C over C++.

I do it more like

ch << "Hello there" << endl;

Pretty convenient and easy stuff, but really all a matter of semantics
(and some argue a little speedier than printf).  However, you can do
something similar in C with stdargs anyways, like this:

#include <stdarg.h>

void Send_to_char(struct char_data *ch, const char * const messg, ...)
  if (!ch->desc || !messg)

  va_list argptr;
  va_start(argptr, messg);
  vsprintf(buf3, messg, argptr);

  SEND_TO_Q(buf, ch->desc);

Now you have a send_to_char that works like printf so you can do:

Send_to_char(ch, "You see %d %s and a silly example!\r\n", num, str);

and pretty much use as many args as you'd like (well the limit is whatever
it is for printf).

This is also the way you'd want to set up a function to take a variable
amount of arguments as someone pointed out previously.
