FUNCTION
<<puts>>---write a character string
 
INDEX
	puts
INDEX
	_puts_r
 
ANSI_SYNOPSIS
	#include <stdio.h>
	int puts(const char *<[s]>);
 
	int _puts_r(struct _reent *<[reent]>, const char *<[s]>);
 
TRAD_SYNOPSIS
	#include <stdio.h>
	int puts(<[s]>)
	char *<[s]>;
 
	int _puts_r(<[reent]>, <[s]>)
	struct _reent *<[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>>.
