qt_dictionary_iterator_get(3)

💖 qt_dictionary_iterator_get — the libqthread dictionary iterator glow-up 💖

okay bestie, so this one lives in libqthread (yes, that libqthread), and it's a lil function called qt_dictionary_iterator_get. She's manual section 3, so you already know she's a library call. Let's get into it 🫶

✨ NAME ✨

qt_dictionary_iterator_get — retrieves the indicated entry in the dictionary. that's it, that's the whole job. she grabs the thing your iterator is pointing at. iconic behavior honestly 👑

🌸 SYNOPSIS 🌸

#include <qthread/dictionary.h>

list_entry *
qt_dictionary_iterator_get (const qt_dictionary_iterator *iter);

so you include the header, you pass in a const qt_dictionary_iterator * called iter, and she hands you back a list_entry *. clean. simple. slay 💅

🦋 DESCRIPTION 🦋

This function retrieves the entry indicated by the iterator iter.

that's literally the whole description and like… respect for the brevity ngl. you give her an iterator, she gives you the entry it's pointing at. main character energy, no notes ✨

🎀 RETURN VALUES 🎀

Returns a key/value pair, if there is one. 💖

okay so here's the part where you gotta pay attention bestie, because the concurrency situation is a little unhinged. 😭

In racy concurrent situations, if the item indicated by the iterator was deleted from the dictionary, multiple results may happen. and like, she's not gonna pick one for you, she's just gonna do something. the possibilities are:

• The next element in the dictionary may be returned,
• or NULL may be returned,
• OR an error may be returned.

However — and this is the important part, no cap — it may not crash. 🫶

so like, chaotic? yes. undefined-ish vibes? sure. but crashing? she would NEVER. periodt 💅
