Hmmm. How 'bout this (off the top of my head, and not actually tested):

/* tee.c - do a unix-style tee */
#include <stdio.h>
#include <stdlib.h>
void main(int argc, char *argv)
{
  FILE *TeeFile;
  char InputLine[4096];
  
  /* open the tee file */
  TeeFile = fopen(argv[0], "w");

  /* grab lines until we have no more */
  while (gets(InputLine)) {
    
    puts(InputLine);
    fputs(InputLine, TeeFile);
    fputc('\n', TeeFile);
  }

  fclose(TeeFile);
}
