KHTML_ELEMAT(3)

💖 NAME 💖

okay so bestie, this is khtml_elemat — get element stack depth of kcgihtml. It lives in KHTML_ELEMAT(3), from the Library Functions Manual, and it's literally the tiny function that tells you how deep the element stack goes. iconic ✨

---

📚 LIBRARY 📚

The library is “libkcgihtml” — yes bestie, that one 🫶

---

🦋 SYNOPSIS 🦋

Include these first, then call it like this:

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

size_t
khtml_elemat(const struct khtmlreq *req);

---

🌸 DESCRIPTION 🌸

Gets the current depth of the element stack of req, which is initialised with khtml_open(3). This is usually used with khtml_closeto(3). the way that little pairing just works 💅

If called before opening any element contexts (i.e., a depth of zero), a subsequent khtml_closeto(3) will close all open scopes. no cap, that's the whole vibe check 🦋

---

🎀 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);

💀 CAVEATS 💀

real talk: If called in a scope that's subsequently closed, then a new scope reopened and filled in, a corresponding khtml_closeto(3) will unwind the stack to the new scope. In other words this does not identify a savepoint: it's merely the scope depth. so like, don't treat it as a savepoint bestie, it's just depth energy 😭
