CLFINISH(3clc)

💖 CLFINISH — bestie, we wait 💖

okay so this is a page from the OpenCL Manual (that's the 3clc section, iykyk), and it's all about clFinish. She's the friend who makes everyone wait until the whole group is ready. No cap.

---

✨ NAME ✨

clFinish — blocks until all previously queued OpenCL commands in a command-queue are issued to the associated device and have completed.

Like. That's the whole personality. She waits. Periodt.

cl_int clFinish(cl_command_queue command_queue);

---

🦋 NOTES 🦋

So here's the vibe: clFinish blocks until all previously queued OpenCL commands in command_queue are issued to the associated device and have completed.

She does not return until all previously queued commands in command_queue have been processed and completed. Literally not a single one left behind. 🫶

Also — and this is the iconic part — clFinish is also a synchronization point. Main character energy fr.

---

🌸 ERRORS 🌸

She returns CL_SUCCESS if the function call was executed successfully. Slay. Otherwise, bestie, she's handing you one of these:

• CL_INVALID_COMMAND_QUEUE — if command_queue is not a valid command-queue. 💀
• CL_OUT_OF_HOST_MEMORY — if there is a failure to allocate resources required by the OpenCL implementation on the host.
• CL_OUT_OF_RESOURCES — if there is a failure to allocate resources required by the OpenCL implementation on the device.
