KXML_PUTC(3)

🌸 NAME 🌸

okay so bestie, this is KXML_PUTC(3) — the manual page for kxml_putc, and the NAME is literally kxml_putc — put character content for kcgixml 💅. That's the whole vibe, periodt.

🎀 LIBRARY 🎀

It lives in the library libkcgixml — yes, the libkcgixml, the one with the fancy quotes in the original, slay ✨.

✨ SYNOPSIS ✨

Like, here's the exact incantation, no cap:

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

enum kcgi_err
kxml_putc(struct kxmlreq *req, char c);

🦋 DESCRIPTION 🦋

It writes a NUL-terminated string cp to a context req initialised with kxml_open(3) — yes, the page says cp even though the signature above takes char c, iykyk 😭. The character is XML escaped, obvi.

💖 RETURN VALUES 💖

It returns an enum kcgi_err that tells you the error state, bestie. The options are:

• KCGI_OK — success, not an error. we love a win 🎉
• KCGI_ENOMEM — internal memory allocation failure. oof 😭
• KCGI_HUP — the output connection has been terminated. For FastCGI connections, the current connection should be released with khttp_free(3) and the parse loop reentered. important!
• KCGI_FORM — the connection is still expecting headers with khttp_head(3). This 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 the parse loop reentered. don't skip the body, bestie.
• KCGI_SYSTEM — internal system error writing to the output stream. 💀

🌈 EXAMPLES 🌈

The following outputs a simple XML page. It assumes r is a struct kreq pointer. For brevity, it does not do any error checking. copy-paste responsibly 🫶

             const char *const elems[] =
               { "foo", "bar", "baz" };
             khttp_head(r, kresps[KRESP_STATUS],
               "%s", khttps[KHTTP_200]);
             khttp_head(r, kresps[KRESP_CONTENT_TYPE],
               "%s", kmimetypes[KMIME_TEXT_XML]);
             khttp_body(r);
             kxml_open(&req, r, elems, 3);
             kxml_push(&req, 0); /* foo */
             kxml_putc(&req, 'H');
             kxml_putc(&req, 'i');
             kxml_putc(&req, '!');
             kxml_close(&req);
