Re: [PLUG] Ncurses

[Kyle Burton <mortis@voicenet.com>]

O'Reilly has a good book on Nucrses...

This is a horrible way of going about it, but, you can ungetc() on stdin:
/* */
#include <stdio.h>

int main(int argc,char**argv)
{
  ungetc('X',stdin);
  printf("got: %c\n",getc(stdin));
  printf("got: %c\n",getc(stdin));
  printf("got: %c\n",getc(stdin));
  return 0;
}
/* */

I'll see if I can dig up anything else...
