# clReleaseSampler(3clc)

Decrements the sampler reference count.

## NAME

clReleaseSampler - Decrements the sampler reference count.

##

**cl\_int clReleaseSampler(cl\_sampler** *sampler***);**

## PARAMETERS

*sampler*

Specifies the *sampler* being retained.

## NOTES

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.

## ERRORS

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.
