CAPNG_SAVE_STATE(3)

💖 CAPNG_SAVE_STATE(3) 💖

okay bestie, so we're in the Libcap-ng API corner of the manual pages, and today's main character is capng_save_state. she's a lil function, she's lowkey iconic, and she's here to let you snapshot the library's whole vibe before somebody else messes with it. periodt. 🎀

✨ NAME ✨

capng_save_state — get the internal library state 🫶

🌸 SYNOPSIS 🌸

#include <cap-ng.h>

void *capng_save_state(void);

like, that's it. no args, she just returns.

🦋 DESCRIPTION 🦋

so capng_save_state is a function that hands you back a pointer to the internal state of the libcap-ng library. it's giving "peek behind the curtain" energy. 👑

but listen — that pointer should be considered opaque and it is not for alteration directly. do not touch. do not poke. do not rearrange her insides, bestie, i'm so serious. 💅

when do you use this? literally the perfect scenario: when you suspect a third party library may use libcap-ng also and you wanna make sure it doesn't alter something important. you save your state, you let the other library do its lil thing, and your important stuff stays untouched. main character protecting her own peace. ✨

one thing to know: this function is not available in the python bindings. so if you're in python-land, this one isn't for you, sorry babes 😭

💜 RETURN VALUE 💜

• NULL on failure — the sad path 💀
• a non-NULL pointer otherwise — the slay path 🔥

⭐ NOTES ⭐

the structure returned by capng_save_state is malloc'd — so yeah, it should be free'd if not used. don't just leave her hanging in memory forever, that's rude to your process. free your girl. 🧚
