QueryPackage(3z)

💖 QueryPackage(3z) 💖

okay bestie, welcome to the z88dk Programmer's Manual and today's main character is QueryPackage — she opens shared libraries/packages and she does it flawlessly. let's get into it 🦋

---

✨ NAME ✨

QueryPackage — open a shared library/package 👑

---

✨ SYNOPSIS ✨

#include <z88.h>

bool_t QueryPackage(char package, char major , char minor);

like yes, that's the whole vibe. one include, one call. 🎀

---

✨ DESCRIPTION ✨

so the QueryPackage() function does two things, and honestly? she ate.

1. she checks the shared package package
2. she makes it available for use — with a version of at least minor.minor

it's giving "let me verify you exist and then let you in the door" 💅

here's the order of operations, no cap: the function initially checks for the presence of the package subsystem itself, and only then does she proceed to check for the specified package. two-step verification, very demure.

oh and if you don't care about version checking at all? just pass minor and major as 0 and version checking gets disabled. lowkey the easiest shortcut ever. ✨

---

✨ RETURN VALUE ✨

• 0 = failure 😭
• 1 = success 🎉

and here's the iconic part: the carry flag is set accordingly, which means you can use the non-standard iferror { ... } construct to check for success. iykyk. 🫶

not me reminding you that iferror is non-standard — it's a z88dk thing, bestie, don't try it at home (or in a different compiler).
