KHTML_ELEMAT(3)

💖 NAME 💖

okay so welcome to KHTML_ELEMAT(3), straight outta the Library Functions Manual — this page is literally about khtml_closeto, and its whole job is to close element contexts of kcgihtml to a given depth. no cap. 🫶

🌸 LIBRARY 🌸

this cutie lives in the library: “libkcgihtml” ✨

🦋 SYNOPSIS 🦋

#include <sys/types.h>
#include <stdarg.h>
#include <stdint.h>
#include <kcgi.h>
#include <kcgihtml.h>

enum kcgi_err
khtml_closeto(struct khtmlreq *req, size_t pos);

🎀 DESCRIPTION 🎀

bestie, here's the vibe: khtml_closeto closes element scopes of req — which you initialised with khtml_open(3) — up to but not including the depth pos. 🌈 The depth is usually obtained with khtml_elemat(3), iykyk.

If you give it a pos that's deeper than or immediately within the current scope, it does nothing and returns success. literally no drama. 💅

🔥 RETURN VALUES 🔥

It returns an enum kcgi_err indicating the error state. here's the whole menu:

• 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);
             pos = khtml_elemat(&req); /* save at html */
             khtml_elem(&req, KELEM_HEAD);
             khtml_elem(&req, KELEM_TITLE);
             khtml_puts(&req, "Hello, world.");
             khtml_closeto(&req, pos); /* to html */
             khtml_closeelem(&req, 1); /* head */
             khtml_elem(&req, KELEM_BODY);
             khtml_puts(&req, "Hello, world");
             khtml_close(&req);
