KHTML_ELEMAT(3)

✨ NAME ✨

okay so this page is KHTML_ELEMAT(3), straight outta the Library Functions Manual, and the main character is khtml_closeelem — close element contexts of kcgihtml. slay. 💅

🦋 LIBRARY 🦋

the library is “libkcgihtml” 💖

🌸 SYNOPSIS 🌸

bestie, include the headers like this:

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

enum kcgi_err
khtml_closeelem(struct khtmlreq *req, size_t nclose);

🎀 DESCRIPTION 🎀

okay so khtml_closeelem() closes nclose element scopes of req, which you initialised with khtml_open(3). Those scopes are opened with khtml_attr(3), khtml_attrx(3), or khtml_elem(3). 🫶

Scopes for “void” elements (self-closing, like KELEM_LINK) or KELEM_DOCTYPE close immediately and should not be explicitly closed. do not come for them, they're already gone 💀

If nclose is zero or greater than the number of open scopes, all scopes are closed. periodt. ✨

💖 RETURN VALUES 💖

Returns an enum kcgi_err indicating the error state. here's the vibe check:

• 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. no cap, keep it simple bestie 🌈

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_HEAD);
khtml_elem(&req, KELEM_TITLE);
khtml_puts(&req, "Hello, world.");
khtml_closeelem(&req, 2); /* title, head */
khtml_elem(&req, KELEM_BODY);
khtml_elem(&req, KELEM_P);
khtml_puts(&req, "Hello, world");
khtml_closeelem(&req, 1); /* p */
khtml_elem(&req, KELEM_P);
khtml_puts(&req, "Another hello, world");
khtml_close(&req);
