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.
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 non-locking 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 non-negative number on
success, or EOF on error.
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.
