C Specification

To release a sampler object, call the function

// Provided by CL_VERSION_1_0
cl_int clReleaseSampler(
    cl_sampler sampler);

Parameters

  • sampler specifies the sampler to be released.

Description

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.

clReleaseSampler returns CL_SUCCESS if the function is executed successfully. Otherwise, it returns one of the following errors:

  • CL_INVALID_SAMPLER if sampler is not a valid sampler object.

  • CL_OUT_OF_RESOURCES if there is a failure to allocate resources required by the OpenCL implementation on the device.

  • CL_OUT_OF_HOST_MEMORY if 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.
