khtml_write — put
content data for kcgihtml
khtml_write(const char *buf,
size_t sz, void *arg);
Writes binary data buf of length
sz to a context arg, a
struct khtmlreq initialised with
khtml_open(3) and passed as an opaque pointer. If
sz is zero, does nothing and returns success. All of
the content is HTML escaped, for example, the left-angle bracket
"<" is rendered as "<".
Returns an enum kcgi_err indicating the error state.
- Success (not an error).
- Internal memory allocation failure.
- The output connection has been terminated. For FastCGI connections, the current connection should be released with khttp_free(3) and parse loop reentered.
- 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.
- Internal system error writing to the output stream.
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_write("Hello, world.", 13, &req); khtml_close(&req);
The referenced HTML5 standard is HTML5.2.
