FUNCTION
<<puts>>---write a character string
INDEX
puts
INDEX
_puts_r
ANSI_SYNOPSIS
#include <stdio.h>
int puts(const char *<[s]>);
int _puts_r(void *<[reent]>, const char *<[s]>);
TRAD_SYNOPSIS
#include <stdio.h>
int puts(<[s]>)
char *<[s]>;
int _puts_r(<[reent]>, <[s]>)
char *<[reent]>;
char *<[s]>;
DESCRIPTION
<<puts>> writes the string at <[s]> (followed by a newline, instead of
the trailing null) to the standard output stream.
The alternate function <<_puts_r>> is a reentrant version. The extra
argument <[reent]> is a pointer to a reentrancy structure.
RETURNS
If successful, the result is a nonnegative integer; otherwise, the
result is <<EOF>>.
PORTABILITY
ANSI C requires <<puts>>, but does not specify that the result on
success must be <<0>>; any non-negative value is permitted.
Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
<<lseek>>, <<read>>, <<sbrk>>, <<write>>. */
