To retain a kernel object, call the function
cl_int clRetainKernel( cl_kernel kernel);
kernel is the kernel object to be retained.
The kernel reference count is incremented.
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.
clCreateKernel or clCreateKernelsInProgram do an implicit retain.
