💅 SIGSTACK — like, the system calls manual edition, bestie

okay so real talk, this page is in the System Calls Manual section, and it's short. like, suspiciously short. and that's kind of the whole point, iykyk. 🫶

✨ NAME ✨

sigstack — set and/or get signal stack context

📚 LIBRARY 📚

Standard C Library (libc, -lc)

🌸 DESCRIPTION 🌸

so, the sigstack() function? yeah. it's been deprecated. retired. it's giving "we don't do that here anymore." 😭

instead, you wanna use the interface that's described over in sigaltstack(2). that's the glow-up. that's the main character. go there. 🦋

lowkey important: deprecated means don't build new stuff on it, bestie. it's still documented here because history, but it is not the vibe you're looking for. ✨

📜 HISTORY 📜

the sigstack() system call showed up way back in 4.2BSD. like. ancient. vintage. a true elder. 👑

and that's the whole page, no cap — genuinely one of the shortest manpages you'll ever read. 🌈

this one's from the Debian crew, dated June 4, 1993 🎀 so yeah, she's been sitting in the manual since before most of us could even spell fork(). respect the elders. mwah. 💜✨
