hook_config_section(3alleg4)

✨ hook_config_section — Allegro manual edition 💅

okay bestie, welcome to the Allegro game programming library, section 3alleg4 🎀 (yes we're doing manpage numbers, it's giving old-school, we love her).

💖 NAME 💖

hook_config_section — hooks a configuration file section with your own custom handlers 🪝✨ (Allegro game programming library, obvs 💜)

🌸 SYNOPSIS 🌸

#include <allegro.h>

void hook_config_section(const char *section, int (*intgetter)(const char *name, int def), const char *(*stringgetter)(const char *name, const char *def), void (*stringsetter)(const char *name, const char *value));

🦋 DESCRIPTION 🦋

so basically 💅 this function takes control of the config file section you name. like, full custody. your hook functions get to handle that section instead of the normal disk file access. the way that it just... reroutes everything, iconic.

if both the getter and setter functions are NULL, then a hook that's currently there gets unhooked 🫶 (we're letting her go, respectfully).

hooked functions have the highest priority. periodt. so if a section is hooked, the hook will always be called — which means you can literally hook a '#' section, and even override_config_file() cannot override a hooked section 😭🔥 that's main character energy, nobody's touching her.

here's the whole vibe in code form 🍓:

int decode_encrypted_int(const char *name, int def)
{
   ...
}

const char *decode_encrypted_string(const char *name, const char *def)
{
   ...
}

void encode_plaintext_string(const char *name, const char *value)
{
   ...
}

int main(int argc, char *argv[])
{
   ...
   /* Make it harder for users to tinker with the high scores. */
   hook_config_section("high_scores", decode_encrypted_int,
      decode_encrypted_string, encode_plaintext_string);
   ...
} END_OF_MAIN()

like yes, encrypt the high scores, protect the vibes, gatekeep the leaderboard 🔐👑

heads up bestie: the '#' section thing is real and it's powerful. hook it and nothing overrides it, not even override_config_file(). use that knowledge wisely, queen 💅✨
