|KHTML_OPEN(3)||Library Functions Manual||KHTML_OPEN(3)|
khtml_open — open
khtml_open(struct khtmlreq *req,
struct kreq *r, int opts);
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.
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_puts(&req, "Hello, world"); khtml_close(&req);
The referenced HTML5 standard is HTML5.2.
