PATCOMPILE(3)

💖 PATCOMPILE(3) — Schily´s LIBRARY FUNCTIONS 💖

okay so bestie, this is the PATCOMPILE(3) page from Schily´s LIBRARY FUNCTIONS, and it's literally about getting your matching pattern compiled and ready to slay. ✨

🌸 NAME 🌸

patcompile() — compiles a matching pattern. That's it, that's the whole vibe: pattern goes in, compiled internal form comes out. 💅

✨ SYNOPSIS ✨

int patcompile(pattern, length, aux)
     char *pattern;
     int length;
     int aux[];

🦋 DESCRIPTION 🦋

patcompile() takes a pattern and compiles it into an internal form — the kind of glow-up that patmatch(3) can actually use. 🔥

It scans the string at pattern with size length. Then it fills the array aux with state information for patmatch(3). No cap, aux should have at least length elements — like, at minimum, bestie, don't skimp. 🫶

🎀 RETURNS 🎀

• It returns 0 if the pattern contains an error. Sad girl hours, the compile did not eat. 😭
• Any other values should be passed to patmatch(3) as the alt argument. That's the handoff, iykyk. 💫

🌈 SEE ALSO 🌈

• match(1)
• For a description of the regular expressions. (The original page says "ot" instead of "of" — a tiny typo moment, but the info is still giving. 🙈)

👑 NOTES 👑

The pattern matching functions are based on ones presented by Martin Richards in "A Compact Function for Regular Expression Pattern Matching", Software-Practice and Experience vol 9, 527-534 (1979). Academic icon behavior, honestly. 🧚
