PCRE2_CODE_COPY(3)

💖 NAME 💖

okay so bestie, this page is PCRE2_CODE_COPY(3) and it lives in the Library Functions Manual — it's all about PCRE2 — Perl-compatible regular expressions (revised API). iconic, honestly. ✨

---

🌸 SYNOPSIS 🌸

#include <pcre2.h>

pcre2_code *pcre2_code_copy_with_tables(const pcre2_code *code);

---

🦋 DESCRIPTION 🦋

so this function makes a copy of the memory used for a compiled pattern, but it excludes any memory used by the JIT compiler. no cap. 🫶

without a subsequent call to pcre2_jit_compile(), the copy can be used only for non-JIT matching. periodt.

unlike pcre2_code_copy(), a separate copy of the character tables is also made, with the new code pointing to it. the way that's lowkey important iykyk 💅

this memory will be automatically freed when pcre2_code_free() is called. slay, no manual cleanup drama. 🎀

the yield of the function is NULL if code is NULL or if sufficient memory cannot be obtained. 😭

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 bestie, they're giving main character energy. 👑

fr fr: keep the JIT situation in mind — without pcre2_jit_compile(), that copy is only for non-JIT matching. 💀
