CAPNG_CAPABILITY_TO_NAME(3)

✨ CAPNG_CAPABILITY_TO_NAME ✨

okay bestie, so this one lives in section 3 of the manual (that's the library functions section, iykyk 💅), and it's part of the Libcap-ng API. it's literally called capng_capability_to_name and it does exactly one (1) thing, but it does it flawlessly. no cap.

🌸 NAME 🌸

capng_capability_to_name — convert capability integer to text 🦋

🎀 SYNOPSIS 🎀

#include <cap-ng.h>

const char *capng_capability_to_name(unsigned int capability);

like, you include the header, you call the function, you get a string. it's giving effortless. periodt.

💖 DESCRIPTION 💖

okay so here's the vibe. capng_capability_to_name takes the integer you pass in and looks it up to see what its text string representation would be. that's it. that's the whole plot. 🌈

the integer you hand over must be in the valid range defined in linux/capability.h — don't be out here passing random numbers, bestie, the range is real and it matters. 🫶

the string that comes out is the same as the define text from linux/capability.h with the CAP_ prefix removed and lower case. so like, the define gets a little makeover and shows up in its lowercase era. ✨

and why do we care? because this is useful for taking an integer representation and converting it to something more user friendly for display. nobody wants to stare at a raw number, we want the cute text version. main character energy fr fr. 👑

🦋 RETURN VALUE 🦋

this returns a NULL pointer on failure 😭 and the correct string otherwise 💖

like, that's it. success = string, failure = NULL. know the difference, it's important. 💀

ok so quick recap for the girlies: pass in a valid capability integer from linux/capability.h, get back the lowercase, CAP_-stripped string version, or NULL if it went sideways. that's the whole thing. slay. 💅
