vpSetClientData(3)

💖 vpSetClientData — bestie edition 💖

ok so this is a page from the Library Functions Manual, section 3, and it's all about vpSetClientData ✨

🌸 NAME 🌸

vpSetClientData — define a client data pointer 🫶

🎀 SYNOPSIS 🎀

#include <volpack.h>

vpResult
vpSetClientData(vpc, client_data)
    vpContext *vpc;
    void *client_data;

✨ ARGUMENTS ✨

• vpc — the VolPack context you got from vpCreateContext. like, your whole lil setup lives in there 💅
• client_data — a pointer to your own application-specific client data. literally yours, your stuff, your vibe 🌈

🦋 DESCRIPTION 🦋

ok so here's the tea: vpSetClientData stores a pointer to application-specific client data inside the VolPack context. that's it. that's the whole job 🫶

and why would you want that? because this pointer gets passed to some of the callback routines — go peek at vpSetCallback(3) for the deets — which lets your app define its own state variables. main character energy: your state, your rules 👑

lowkey important: VolPack itself does not use this pointer. not even a little. it's just holding it for you like a bestie holding your iced coffee 🧊 it's purely for you, iykyk ✨

💀 ERRORS 💀

ngl this one is so chill — the return value is always VP_OK. no drama, no errors, no nothing. periodt 💅
