DESCRIPTION
sl@0
    49
<<puts>> writes the string at <[s]> (followed by a newline, instead of
sl@0
    50
the trailing null) to the standard output stream.
sl@0
    51
sl@0
    52
The alternate function <<_puts_r>> is a reentrant version.  The extra
sl@0
    53
argument <[reent]> is a pointer to a reentrancy structure.
sl@0
    54
sl@0
    55
RETURNS
sl@0
    56
If successful, the result is a nonnegative integer; otherwise, the
sl@0
    57
result is <<EOF>>.
sl@0
    58
sl@0
    59
PORTABILITY
sl@0
    60
ANSI C requires <<puts>>, but does not specify that the result on
sl@0
    61
success must be <<0>>; any non-negative value is permitted.
sl@0
    62
sl@0
    63
Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
sl@0
    64
<<lseek>>, <<read>>, <<sbrk>>, <<write>>.  */
