Decrements the sampler reference count.
cl_int clReleaseSampler(cl_sampler sampler)
The sampler object is deleted after the reference count becomes zero and commands queued for execution on a command-queue(s) that use
sampler have finished.
Using this function to release a reference that was not obtained by creating the object or by calling
clRetainSampler causes undefined behavior.
CL_SUCCESS if the function is executed successfully.
Otherwise, it returns one of the following errors:
sampleris not a valid sampler 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.
