C Specification

To retain a kernel object, call the function

cl_int clRetainKernel(
    cl_kernel kernel);

Parameters

  • kernel is the kernel object to be retained.

Description

The kernel reference count is incremented.

clRetainKernel 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.

clCreateKernel or clCreateKernelsInProgram do an implicit retain.
