KHTML_OPEN(3)		    Library Functions Manual		 KHTML_OPEN(3)

NAME
       khtml_open -- open kcgihtml context

LIBRARY
       library "libkcgihtml"

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

       enum kcgi_err
       khtml_open(struct khtmlreq *req,	struct kreq *r,	int opts);

DESCRIPTION
       Zeroes  and  initialises	 a new context req with	the underlying kcgi(3)
       context r as allocated with khttp_parse(3) or khttp_fcgi_parse(3).   It
       should  only  be	 called	 after	khttp_body(3).	 If  opts  is	set to
       KHTML_PRETTY, the output	is lightly "pretty-printed" with newlines  and
       indentation spaces.  By default,	output is all on one line.

       If  kcgi_writer_disable(3)  has been called, the	process	will be	killed
       with an uncatchable signal.

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  connec-
	    tions,   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).  In-
	    dicates that khttp_body(3) did not return with success or was  not
	    invoked.   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_puts(&req, "Hello, world");
	     khtml_close(&req);
