✨ CLRETAINCOMMANDQUEUE ✨

okay bestie, buckle up 💖 this is a page from the OpenCL Manual (that's the 3clc collection, iykyk) and it's literally about making a command-queue's reference count go ⬆️ up by one. tiny function, big main character energy. 👑

💅 NAME 💅

clRetainCommandQueue — increments the command_queue reference count. no cap. 🫶

cl_int clRetainCommandQueue(cl_command_queue command_queue);

🎀 PARAMETERS 🎀

  • command_queue — the command-queue you wanna retain. that's it, that's the whole vibe. ✨

💖 NOTES 💖

so here's the tea 🍓: clCreateCommandQueue(3clc) does an implicit retain already. super helpful for 3rd party libraries, which typically just get a command-queue handed to them by the application, like "here girl, hold this." 🙈

but plot twist 😭 — it's totally possible that the application goes and deletes that command-queue without informing the library. rude?? yes. does it happen? also yes.

and that's exactly why letting functions attach to (i.e. retain) and release a command-queue solves the problem of a command-queue being used by a library no longer being valid. like, the library gets to say "bestie i'm still using this" and the queue stays alive. periodt. 💅

🚨 ERRORS 🚨

Returns CL_SUCCESS if the function executed successfully 🎉, or one of the errors below:

  • CL_INVALID_COMMAND_QUEUE — if command_queue is not a valid command-queue. it's giving "who is she?" 💀
  • 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. 🫠
