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(char *s);
       int ungetc(int c, FILE *stream);

DESCRIPTION
       fputc() writes the character c, cast to an unsigned  char,
       to stream.

       fputs()  writes the string s to stream, without its trail-
       ing '\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  std-
       out.

       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.

RETURN VALUES
       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 non - negative number on  suc-
       cess, or EOF on error.


CONFORMS TO
       ANSI - C, POSIX.1

BUGS
       It  is not advisable to mix calls to output functions from
       the stdio library with low - level calls  to  write()  for
       the  file  descriptor  associated  with  the  same  output
       stream; the results will be undefined  and  very  probably
       not what you want.
