💅 drm_syncobj_create(9) — the Kernel API Manual glow-up ✨

okay so bestie, welcome to the Kernel API Manual entry for drm_syncobj_create(9) — yes the whole page is named after the function, we love a title drop 👑

---

🌸 NAME 🌸

drm_syncobj_create — literally creates a brand new syncobj for you, no cap 💫

---

✨ SYNOPSIS ✨

int drm_syncobj_create (struct drm_syncobj **out_syncobj , uint32_t
       flags , struct dma_fence *fence );

---

🎀 ARGUMENTS 🎀

• out_syncobj — the syncobj that gets returned to you 🫶 like, this is where your brand-new baby comes back out.
• flags — the DRM_SYNCOBJ_* flags, periodt.
• fence — if this is non-NULL, the syncobj will represent this fence 🔥 (if it is NULL, it just doesn't, iykyk).

---

🦋 DESCRIPTION 🦋

This is the first function to create a sync object — like the origin story, the main character energy of syncobj creation 👑.

After creating it, drivers probably want to make it available to userspace, either through drm_syncobj_get_handle or drm_syncobj_get_fd 💖. So like, you made it, now go introduce it to the people.

Returns 0 on success or a negative error value on failure 😭 bestie if it's negative, something went wrong, fr fr.

ngl the return value check is not optional — 0 means slay, negative means go read the error and cope 🙈
