Decrements the command_queue reference count.
cl_int clReleaseCommandQueue(cl_command_queue command_queue);
command_queue
Specifies the command-queue to release.
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.
Returns CL_SUCCESS if the function is executed successfully. Otherwise, it returns one of the following:
CL_INVALID_COMMAND_QUEUE if command_queue is 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.
