KHTML_CLOSE(3)

NAME
khtml_close - close kcgihtml context

LIBRARY
libkcgihtml

SYNOPSIS
#include <sys/types.h>
#include <stdarg.h>
#include <stdint.h>
#include <kcgi.h>
#include <kcgihtml.h>
enum kcgi_err
khtml_close(struct khtmlreq *req);

DESCRIPTION
Closes req, initialised with khtml_open(3). All scopes opened with khtml_attr(3), khtml_attrx(3), or khtml_elem(3) are automatically closed. After this, req may no longer be used.

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). Indicates 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);
