sys_rt_sigqueueinfo(9)

💖 NAME 💖

okay so welcome to sys_rt_sigqueueinfo(9) from the Kernel API Manual — and the name-line tea is literally sys_rt_sigqueueinfo - send signal information to a signal. that's the whole moment, bestie, and we're keeping it exactly as it is ✨

✨ SYNOPSIS ✨

long sys_rt_sigqueueinfo (pid_t pid , int sig , siginfo_t __user * uinfo
);

🎀 ARGUMENTS 🎀

• pid — the PID of the thread, periodt. that's the pid you're pointing at 🫶
• sig — the signal to be sent, no cap. it's giving "which signal goes out" 💅
• uinfo — the signal info to be sent, bestie. this is the siginfo_t __user * payload vibe 🌸
