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 '\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 associated with the same output stream; the results will be undefined and very probably not what you want.
