🌸 event_trigger_empty_param(9) 🌸

okay so bestie, welcome to the Kernel API Manual entry for event_trigger_empty_param — this one is lowkey a tiny helper, but it’s iconic in its own way 💅. We’re doing a full vibe check on it, no skipped details, periodt.

✨ NAME ✨

  • event_trigger_empty_param — check whether the param is empty 🫶

🎀 SYNOPSIS 🎀

Here’s the exact signature, bestie — do not improvise it:

bool event_trigger_empty_param (const char *param );

🦋 ARGUMENTS 🦋

  • param — The trigger param string. That’s the whole argument, and yes, it’s literally called param 😌.

💖 DESCRIPTION 💖

okay so here’s the lore: the event trigger callback implementations pass in param as a parameter. It corresponds to the string following the command name minus the command name. iykyk 🌀.

This function can be called by a callback implementation for any command that requires a param; a callback that doesn't require a param can ignore it. fr fr — if your callback doesn’t need a param, you can just ignore it, no drama 🫶.

🌈 RETURN 🌈

  • true if this is an empty param, false otherwise ✨
