kjson_open — open
kjson_open(struct kjsonreq *req,
struct kreq *r);
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 JSON 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_APP_JSON]); khttp_body(r); kjson_open(&req, r); kjson_obj_open(&req); kjson_putstringp(&req, "foo", "bar"); kjson_close(&req);
