To release a command-queue, call the function
The command_queue reference count is decremented.
After the command_queue reference count becomes zero and all commands queued to command_queue have finished (eg. kernel-instances, 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.
CL_SUCCESS if the function is executed
Otherwise, it returns one of the following errors:
CL_INVALID_if command_queue is not a valid command-queue.
CL_OUT_if there is a failure to allocate resources required by the OpenCL implementation on the device.
CL_OUT_if there is a failure to allocate resources required by the OpenCL implementation on the host.
OF_ HOST_ MEMORY
