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 trailing ''.

       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.
