KHTML_PRINTF(3) 	     Library Functions Manual		 KHTML_PRINTF(3)

NAME
     khtml_printf -- put variable content for kcgihtml

LIBRARY
     libkcgihtml

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

     enum kcgi_err
     khtml_printf(struct khtmlreq *req, const char *fmt, ...);

DESCRIPTION
     Writes  output according to the given fmt to a context req initialised with
     khtml_open(3).  The format is as for printf(3).

     If fmt is NULL, it does nothing and returns success.  All of the content is
     HTML escaped, for example,  the  left-angle  bracket  "<"	is  rendered  as
     "&lt;".

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  re-
	  leased 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_printf(&req, "%s", "Hello, world.");
	   khtml_close(&req);
