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