PUTS(3)                    Linux Programmer's Manual                   PUTS(3)

NAME
       fputc, fputs, putc, putchar, puts - output of characters and strings
SYNOPSIS
       #include <stdio.h>
       int fputc(int c, FILE *stream);
       int fputs(const char *s, FILE *stream);
       int putc(int c, FILE *stream);
       int putchar(int c);
       int puts(const char *s);
DESCRIPTION
       fputc() writes the character c, cast to an unsigned char, to stream.
       fputs()  writes  the  string  s to stream, without its terminating null
       byte ('\0').
       putc() is equivalent to fputc() except that it may be implemented as  a
       macro which evaluates stream more than once.
       putchar(c); is equivalent to putc(c,stdout).
       puts() writes the string s and a trailing newline to stdout.
       Calls  to the functions described here can be mixed with each other and
       with calls to other output functions from the  stdio  library  for  the
       same output stream.
       For nonlocking counterparts, see unlocked_stdio(3).
RETURN VALUE
       fputc(),  putc()  and  putchar()  return  the  character  written as an
       unsigned char cast to an int or EOF on error.
       puts() and fputs() return a nonnegative number on success,  or  EOF  on
       error.
CONFORMING TO
       C89, C99.
BUGS
       It  is  not  advisable  to mix calls to output functions from the stdio
       library with low-level calls to write(2) for the file descriptor  asso-
       ciated  with  the same output stream; the results will be undefined and
       very probably not what you want.
