ERR_SET_MARK(3)

💅 ERR_set_mark / ERR_pop_to_mark — set marks and pop OpenSSL errors until mark 💅

Hey bestie! Welcome to the ERR_SET_MARK(3) manual page. This is all about marking errors and popping them like it's hot. Let's get into it 💖

✨ NAME ✨

ERR_set_mark, ERR_pop_to_mark — set marks and pop OpenSSL errors until mark

---

🌸 SYNOPSIS 🌸

library “libcrypto” #include <openssl/err.h>

int
ERR_set_mark(void);

int
ERR_pop_to_mark(void);

---

🦋 DESCRIPTION 🦋

Okay so bestie, ERR_set_mark() is literally the main character here. It sets a mark on the current topmost error record—if there is one, no cap. Think of it like putting a pin in your fave outfit so you can come back to it later 💅.

Then ERR_pop_to_mark()? It pops the top of the error stack until it finds that mark. The mark gets removed, periodt. But if there's no mark? The whole stack is gone, bye 💀. So like, careful with that one, fr fr.

---

🎀 RETURN VALUES 🎀

Here's the vibe check on return values:

• ERR_set_mark() returns 0 if the error stack is empty, otherwise 1. Simple.
• ERR_pop_to_mark() returns 0 if there was no mark in the error stack, which implies that the stack became empty (yikes), otherwise 1.

🌈 HISTORY 🌈

Fun fact: ERR_set_mark() and ERR_pop_to_mark() first appeared in OpenSSL 0.9.8 and have been available since OpenBSD 4.5. So they're lowkey iconic at this point, ngl.
