SYSDECODE(3)

💖 SYSDECODE(3) — Library Functions Manual 💖

okay so bestie, this is the Library Functions Manual page for SYSDECODE(3) — yes, the manual name is literally Library Functions Manual, and we're folding it in right here at the top like the main character it is. 💅

✨ NAME ✨

sysdecode — system argument decoding library. that's the whole name, and honestly? it's giving "I give you descriptive names for values around system calls so you don't have to." 🫶

🎀 LIBRARY 🎀

the library is libsysdecode. yes, the LIBRARY section is literally library “libsysdecode” and nothing else. short and iconic. ✨

🌸 SYNOPSIS 🌸

#include <sysdecode.h>

🦋 DESCRIPTION 🦋

okay so the sysdecode library includes several functions that provide descriptive names of values associated with system calls. that's the whole vibe: system-call-adjacent values get descriptive names, and this library is the one handing them to you. no cap, it's useful. 💖

🌈 Supported ABIs 🌈

some functions in this library provide ABI-specific descriptions. the supported ABIs are named by the enum sysdecode_abi enumeration, and here's the whole cast, bestie:

• SYSDECODE_ABI_FREEBSD — Native FreeBSD binaries. Supported on all platforms.
• SYSDECODE_ABI_FREEBSD32 — 32-bit FreeBSD binaries. Supported on aarch64, amd64 and powerpc64.
• SYSDECODE_ABI_LINUX — Linux binaries of the same platform. Supported on amd64, i386, and aarch64.
• SYSDECODE_ABI_LINUX32 — 32-bit Linux binaries. Supported on amd64.
• SYSDECODE_ABI_UNKNOWN — A placeholder for use when the ABI is not known.

periodt. each one is doing its own little ABI thing, and SYSDECODE_ABI_UNKNOWN is literally the "idk yet" placeholder. 🙈
