C Specification

To release a kernel object, call the function

cl_int clReleaseKernel(
    cl_kernel kernel);

Parameters

  • kernel is the kernel object to be released.

Description

The kernel reference count is decremented.

The kernel object is deleted once the number of instances that are retained to kernel become zero and the kernel object is no longer needed by any enqueued commands that use kernel. Using this function to release a reference that was not obtained by creating the object or by calling clRetainKernel causes undefined behavior.

clReleaseKernel returns CL_​SUCCESS if the function is executed successfully. Otherwise, it returns one of the following errors:

  • CL_​INVALID_​KERNEL if kernel is not a valid kernel 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.
