putchar

 NAME
  putchar - output character to stdout (MACRO)

 SYNOPSIS
  #include <stdio.h>

  int r = putchar(c);

 FUNCTION
  putchar() outputs a character to stdout, returning the output
  character unless an error occured.  If an error occured then
  EOF is returned.

 NOTE
  refer to the file_pointer manual page for general information

 EXAMPLE
  /*
   *  copy stdin to stdout using getchar/putchar.  Normally one uses
   *  fread/fwrite, but I'll save that for the fread manual page.
   *
   *  note that I output the initial message to stderr so it does
   *  not get stuck into stdout in case the user has redirected
   *  stdout.
   *
   *  See getc manual page for equivalent example using getc/putc
   */

  #include <stdio.h>

  main()
  {
      int c;

      fputs("Type a couple of lines, then ^ (EOF)n", stderr);
      while ((c = getchar()) != EOF) {
      putchar(c);
      }
      return(0);
  }

 INPUTS
  int c;      character to output, 0 to 255

 RESULTS
  int r;      same as c unless error occured in which case EOF.
