fputc()
writes the character
c,
cast to an
unsigned char,
to
stream.
fputs()
writes the string
s
to
stream,
without its trailing
aq\0aq.
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.
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
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.
