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.

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 success, or EOF on error.

CONFORMING 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.
