✨ NAME ✨

SDL_UploadToGPUBuffer — uploads data from a transfer buffer to a buffer. that's it, that's the vibe 💅

---

🌸 SYNOPSIS 🌸

#include <SDL3/SDL_gpu.h>

void SDL_UploadToGPUBuffer(
    SDL_GPUCopyPass *copy_pass,
    const SDL_GPUTransferBufferLocation *source,
    const SDL_GPUBufferRegion *destination,
    bool cycle);

like. look at her. four little params and she's serving 💖

🦋 DESCRIPTION 🦋

the upload happens on the GPU timeline, okay? so the timing is giving async but make it graphics. and the best part: you may assume that the upload has finished in subsequent commands. no cap. so you don't have to sit there stressing about whether it landed — by the time your next commands roll around, it's done. slay 🔥

🎀 FUNCTION PARAMETERS 🎀

• copy_pass — a copy pass handle. she's the pass doing the copying, obviously 💅
• source — the source transfer buffer, with offset. iykyk, offset included, don't forget it 🙈
• destination — the destination buffer, with offset and size. yes bestie, size too, she's not like the others 👑
• cycle — if true, it cycles the buffer if it's already bound. otherwise it overwrites the data. so like, cycling vs. straight-up overwriting, pick your fighter 🌈
