sys_rt_sigsuspend(9)

💖 sys_rt_sigsuspend 💖

okay so bestie, welcome to the sys_rt_sigsuspend(9) page from the Kernel API Manual, section 9. This one is literally about replacing the signal mask for a value with the @unewset value until a signal is received. No cap, that's the whole vibe.

✨ SYNOPSIS ✨

long sys_rt_sigsuspend (sigset_t __user * unewset , size_t sigsetsize );

🎀 ARGUMENTS 🎀

• unewset — the new signal mask value. That's the fresh mask you're swapping in, bestie.
• sigsetsize — size of sigset_t type. Gotta tell it how big the signal-set situation is.
