KHTML_INT(3)

Okay bestie, you’re looking at KHTML_INT(3) from the Library Functions Manual — the kcgihtml page about putting integer content 💅✨

💖 NAME 💖

khtml_int — put integer content for kcgihtml 🎀

🎀 LIBRARY 🎀

It lives in library “libkcgihtml” 🦋

✨ SYNOPSIS ✨

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

enum kcgi_err
khtml_int(struct khtmlreq *req, int64_t v);

🦋 DESCRIPTION 🦋

Writes an integer v to a context req initialised with khtml_open(3) 🫶

It formats that integer as [-]?[0-9]+ — yes, bestie, optional minus then digits, periodt 💅

🌸 RETURN VALUES 🌸

Returns an enum kcgi_err indicating the error state ✨

• 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);
             khtml_elem(&req, KELEM_BODY);
             khtml_elem(&req, KELEM_P);
             khtml_int(&req, 12345);
             khtml_close(&req);
