KHTML_PUTS(3)	       FreeBSD Library Functions Manual		 KHTML_PUTS(3)

NAME
     khtml_puts	-- put string content for kcgihtml

LIBRARY
     library "libkcgihtml"

SYNOPSIS
     #include <sys/types.h>
     #include <stdarg.h>
     #include <stdint.h>
     #include <kcgi.h>
     #include <kcgihtml.h>

     enum kcgi_err
     khtml_puts(struct khtmlreq	*req, const char *cp);

DESCRIPTION
     Writes a NUL-terminated string cp to a context req	initialised with
     khtml_open(3).  If	cp is NULL, does nothing and returns success.  All of
     the content is HTML escaped, for example, the left-angle bracket "<" is
     rendered as "&lt;".  It does not append a newline like puts(3).

RETURN VALUES
     Returns an	enum kcgi_err indicating the error state.

     KCGI_OK
	  Success (not an error).

     KCGI_ENOMEM
	  Internal memory allocation failure.

     KCGI_HUP
	  The output connection	has been terminated.  For FastCGI connections,
	  the current connection should	be released with khttp_free(3) and
	  parse	loop reentered.

     KCGI_FORM
	  The connection is still expecting headers with khttp_head(3).	 Indi-
	  cates	that khttp_body(3) did not return with success or was not in-
	  voked.  For FastCGI connections, the current connection should be
	  released with	khttp_free(3) and parse	loop reentered.

     KCGI_SYSTEM
	  Internal system error	writing	to the output stream.

EXAMPLES
     The following outputs a simple HTML page.	It assumes r is	a struct kreq
     pointer.  For brevity, it does not	do any error checking.

	   khttp_head(r, kresps[KRESP_STATUS],
	     "%s", khttps[KHTTP_200]);
	   khttp_head(r, kresps[KRESP_CONTENT_TYPE],
	     "%s", kmimetypes[KMIME_TEXT_HTML]);
	   khttp_body(r);
	   khtml_open(&req, r, 0);
	   khtml_elem(&req, KELEM_DOCTYPE);
	   khtml_elem(&req, KELEM_HTML);
	   khtml_elem(&req, KELEM_BODY);
	   khtml_elem(&req, KELEM_P);
	   khtml_puts(&req, "Hello, world.");
	   khtml_close(&req);
