PCRE2_SET_MAX_PATTERN_COMPILED_LENGTH(3)

🎀 PCRE2_SET_MAX_PATTERN_COMPILED_LENGTH(3) 🎀

Library Functions Manual girlies, this one's for you 💅 This page is all about setting a compiled-pattern memory limit in a compile context, and yes, it's as niche and iconic as it sounds.

✨ NAME ✨

PCRE2 - Perl-compatible regular expressions (revised API)

---

🦋 SYNOPSIS 🦋

#include <pcre2.h>

int pcre2_set_max_pattern_compiled_length(
  pcre2_compile_context *ccontext, PCRE2_SIZE value);

---

💖 DESCRIPTION 💖

Okay so picture your compile context, bestie. This function sets, inside that compile context, the maximum size — in bytes — for the memory needed to hold the compiled version of a pattern that's using this context.

The result is always zero. No cap. That's just the vibe.

If a pattern that is passed to pcre2_compile() referencing this context needs more memory than that, an error is generated. Boom. Limit exceeded, not slay.

The default is the largest number that a PCRE2_SIZE variable can hold, which is effectively unlimited. So out of the box, it's giving infinite runway ✨

There is a complete description of the PCRE2 native API in the pcre2api page, and a description of the POSIX API in the pcre2posix page. Go read those if you want the full lore 🫶
