CLRELEASEMEMOBJECT(3clc)

✨ CLRELEASEMEMOBJECT ✨

(that's the 3clc page, bestie — straight out of the OpenCL Manual)

okay so picture this: you've got a memory object, right? and it's out here living its best life with a whole reference count. this function is the "okay girl, you can go now" button. it decrements the memory object reference count 💅

cl_int clReleaseMemObject(cl_mem memobj);

---

🌸 NAME 🌸

clReleaseMemObject — decrements the memory object reference count.

cl_int clReleaseMemObject(cl_mem memobj);

---

💖 NOTES 💖

okay so here's the tea 🫖 — once the memobj reference count hits zero, AND every command that was queued for execution on the command-queue(s) using memobj has finished... then the memory object gets deleted. it's giving "we don't leave until the last guest is gone" energy ✨

and also!! if memobj is a buffer object, memobj literally cannot be deleted until all the sub-buffer objects associated with memobj are deleted first. no skipping the line, bestie 😭

---

🔥 ERRORS 🔥

returns CL_SUCCESS if the function is executed successfully. otherwise it hands you back one of these bad boys:

• CL_INVALID_MEM_OBJECT — if memobj is a not a valid memory object 💀
• CL_OUT_OF_RESOURCES — if there is a failure to allocate resources required by the OpenCL implementation on the device 😭
• CL_OUT_OF_HOST_MEMORY — if there is a failure to allocate resources required by the OpenCL implementation on the host 🙈
