To release a kernel object, call the function
cl_int clReleaseKernel( cl_kernel kernel);
kernel is the kernel object to be released.
The kernel reference count is decremented.
The kernel object is deleted once the number of instances that are retained to kernel become zero and the kernel object is no longer needed by any enqueued commands that use kernel. Using this function to release a reference that was not obtained by creating the object or by calling clRetainKernel causes undefined behavior.
CL_SUCCESS if the function is executed
Otherwise, it returns one of the following errors:
CL_INVALID_KERNELif kernel is not a valid kernel object.
CL_OUT_OF_RESOURCESif there is a failure to allocate resources required by the OpenCL implementation on the device.
CL_OUT_OF_HOST_MEMORYif there is a failure to allocate resources required by the OpenCL implementation on the host.
