PQtypesRegister(3)

💖 PQtypesRegister(3) 💖

okay bestie, we're diving into libpqtypes — the libpqtypes manual, to be exact, and this little function is the gatekeeper you gotta talk to before literally anything else works. no cap.

---

✨ NAME ✨

PQtypesRegister — registers libpqtypes with the libpq event system. that's it, that's the job. 💅

---

🌸 SYNOPSIS 🌸

#include <libpqtypes.h>

int PQtypesRegister(PGconn *conn);

---

💀 DEPRECATED 💀

THIS FUNCTION IS DEPRECATED. like, officially. new applications should use PQinitTypes instead. this function is now just a lil wrapper around PQinitTypes. so if you're starting fresh? go use PQinitTypes, bestie. i'm begging. 🙈

---

🦋 DESCRIPTION 🦋

so here's the tea: libpqtypes makes use of the libpq Event System. and before you can use libpqtypes, you must register libpqtypes as a libpq EventProc. non-negotiable, it's giving prerequisite.

the function takes a PGconn that libpqtypes will be registered with — and here's the important bit — each PGconn requires its own registration. every single one. no sharing, no shortcuts, no "but it worked for the other one". one connection, one registration. periodt. 👑

---

⭐ RETURN VALUE ⭐

• returns zero if it fails 😭
• returns non-zero if it succeeds 🎉

(yes, zero means failure here. i know. we've all been burned by this. vibe check your return values, fr fr.)

🎀 EXAMPLES 🎀

Registering libpqtypes 🌈

this example shows how to register libpqtypes with the libpq event system. iconic behaviour only:

/* call prior to any other libpqtypes functions that operate on conn. */
PQtypesRegister(conn);

see that comment? that's not decoration, that's a warning label. call it prior to any other libpqtypes functions that operate on conn. before. not after. before. 💅
