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>>.
