LIBRARY
library “libkcgihtml”
SYNOPSIS
#include
<sys/types.h>
#include <stdarg.h>
#include <stdint.h>
#include <kcgi.h>
#include <kcgihtml.h>
enum kcgi_err
khttp_entity
(struct kreq *req,
enum entity v);
DESCRIPTION
Writes a named character entity v to a context req initialised with khtml_open(3). The value is formatted as "&#xNNNN;".
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_elem(&req, KELEM_P); khtml_puts(&req, "Hello"); khtml_ncr(&req, KENTITY_hellip); /* ... */ khtml_close(&req);
