for_each_if(9)

✨ NAME ✨

okay so bestie, meet for_each_if — the little helper from the Kernel API Manual (yep, the for_each_if(9) page) for handling conditionals in various for_each macros. That's literally the whole vibe: helper for handling conditionals in various for_each macros. 🎀

🌸 SYNOPSIS 🌸

for_each_if (condition );

🦋 ARGUMENTS 🦋

• condition — the condition to check. That's it, that's the argument. 💅

💖 DESCRIPTION 💖

Typical use, no cap:

#define for_each_foo_bar(x, y) ´
        list_for_each_entry(x, y->list, head) ´
                for_each_if(x->something == SOMETHING)

The for_each_if macro makes the use of for_each_foo_bar less error prone. slay, safety. ✨
