PCRE2_SERIALIZE_GET_NUMBER_OF_CODES(3)

🌸 NAME 🌸

PCRE2 — Perl-compatible regular expressions (revised API). This is the pcre2_serialize_get_number_of_codes(3) page from the Library Functions Manual, and it’s here to help you count the codes in a serialized byte stream. Periodt. 💅

✨ SYNOPSIS ✨

#include <pcre2.h>

int32_t pcre2_serialize_get_number_of_codes(const uint8_t *bytes);

🎀 DESCRIPTION 🎀

Okay so bestie, here’s the tea. The bytes argument must point to a serialized byte stream that was originally created by pcre2_serialize_encode() — though it may have been saved on disc or elsewhere in the meantime. No cap. 🫶

The function returns the number of serialized patterns in the byte stream, or one of these negative error codes:

• PCRE2_ERROR_BADMAGIC — mismatch of id bytes in bytes
• PCRE2_ERROR_BADMODE — mismatch of variable unit size or PCRE version
• PCRE2_ERROR_NULL — the argument is NULL

PCRE2_ERROR_BADMAGIC may mean that the data is corrupt, or that it was compiled on a system with different endianness. 💀

There is a complete description of the PCRE2 native API in the pcre2api page and a description of the serialization functions in the pcre2serialize page. Go read those if you want the full lore. 🦋
