DBM_FILTER::INT32(3perl)

💖 NAME 💖

DBM_Filter::int32 — a filter for DBM_Filter, bestie. Yes that's literally the whole name section, we're moving fast today ✨ (also hi, you're in section 3perl, the Perl Programmers Reference Guide corner of the library, come sit with us 🫶)

---

🎀 SYNOPSIS 🎀

Okay so here's the vibe, copy-paste energy:

use SDBM_File; # or DB_File, GDBM_File, NDBM_File, or ODBM_File
use DBM_Filter ;

$db = tie %hash, ...
$db->Filter_Push('int32');

That's it. That's the whole ritual. You tie like normal, then you push the filter and let it cook 🔥

---

✨ DESCRIPTION ✨

So when do you even need this? Literally only one scenario, and it's a good one 💅

You use this DBM filter when you're interoperating with a C/C++ application that uses a C int as either the key and/or the value in the DBM file. That's the entire job description, no cap.

So like: your C/C++ bestie is out there writing raw C ints into the DBM file, and your Perl side needs to read and write those same things without everything turning into hot garbage 😭. Push 'int32' onto the filter stack and the two of you are finally speaking the same language. Iconic behaviour, honestly.

ngl the key thing here is the word "either" — it's the key, or the value, or both. It's giving flexible 👑
