To release a sampler object, call the function
cl_int clReleaseSampler( cl_sampler sampler);
sampler specifies the sampler to be released.
The sampler reference count is decremented. 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.
CL_SUCCESS if the function is executed
Otherwise, it returns one of the following errors:
CL_INVALID_SAMPLERif sampler is 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.
Using this function to release a reference that was not obtained by creating the object or by calling clRetainSampler causes undefined behavior.
