FUNCTION

<>---write a character string

INDEX

	puts

INDEX

	_puts_r

ANSI_SYNOPSIS

	#include 

	int puts(const char *<[s]>);

	int _puts_r(struct _reent *<[reent]>, const char *<[s]>);

TRAD_SYNOPSIS

	#include 

	int puts(<[s]>)

	char *<[s]>;

	int _puts_r(<[reent]>, <[s]>)

	struct _reent *<[reent]>;

	char *<[s]>;

DESCRIPTION

<> 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 <>.

PORTABILITY

ANSI C requires <>, but does not specify that the result on

success must be <<0>>; any non-negative value is permitted.

Supporting OS subroutines required: <>, <>, <>,

<>, <>, <>, <>.
