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 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.
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.
