cl_int clReleaseCommandQueue(
| cl_command_queue command_queue) |
Notes
After the command_queue reference count becomes zero and all commands
queued to command_queue have finished (e.g., kernel executions,
memory object updates, etc.), the command-queue is deleted.
clReleaseCommandQueue performs an implicit flush to issue any
previously queued OpenCL commands in command_queue.
Using this function to release a reference that was not obtained
by creating the object or by calling
clRetainCommandQueue
causes undefined behavior.
Errors
Returns CL_SUCCESS if the function is executed successfully. Otherwise, it returns one of the following:
- CL_INVALID_COMMAND_QUEUE if
command_queueis not a valid command queue. - 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.
