✨ set_current_blocked(9) ✨

okay bestie, welcome to the set_current_blocked(9) page from the Kernel API Manual — yes, the manual name is folded in right here like a little name tag 🫶. This one is short and iconic, so let’s go.

🌸 NAME 🌸

set_current_blocked — change current->blocked mask. that’s the whole name vibe, fr fr.

🦋 SYNOPSIS 🦋

the signature is giving “one function, no cap”:

void set_current_blocked (sigset_t *newset );

🎀 ARGUMENTS 🎀

• newset — the new mask, periodt.

💅 DESCRIPTION 💅

bestie, do not change ->blocked directly — that is wrong. This helper is the one you use instead, so the process can’t miss a shared signal that we are going to block. no cap, that’s the whole point.

🚨 lowkey important: direct ->blocked edits are wrong; use this helper to keep the process from missing a shared signal we’re about to block.
