KXML_PUTS(3)

✨ NAME ✨

kxml_puts — put string content for kcgixml. This is the KXML_PUTS(3) manual page, a Library Functions Manual moment, and it's lowkey iconic for anyone building XML with kcgixml. 💅

🎀 LIBRARY 🎀

It lives in library “libkcgixml”. That's the whole vibe. ✨

🦋 SYNOPSIS 🦋

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

enum kcgi_err
kxml_puts(struct kxmlreq *req, const char *cp);

🌸 DESCRIPTION 🌸

Okay bestie, here's the tea: kxml_puts writes a NUL-terminated string cp to a context req that was initialised with kxml_open(3). If cp is NULL, it does nothing and returns success — no drama, no error, just vibes. 🫶

All of the content is XML escaped. Also important: it does not append a newline like puts(3) does, so don't expect that little extra line break. periodt.

💖 RETURN VALUES 💖

It returns an enum kcgi_err indicating the error state. Here's the full cast:

• KCGI_OK — Success (not an error). Slay.
• 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 XML page. It assumes r is a struct kreq pointer. For brevity, it does not do any error checking.

             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_puts(&req, "Hello, world");
             kxml_close(&req);
