## Detailed Description

Class interface for cl_kernel.

Note
  Copies of these objects are shallow, meaning that the copy will refer to the same underlying cl_kernel as the original. For details, see clRetainKernel() and clReleaseKernel().

## Constructor & Destructor Documentation

## Kernel() [1/4]

cl::Kernel::Kernel | ( | const Program & | program,
|  | const string & | name,
|  | cl_int * | err = nullptr )

inline

Definition at line 7502 of file opencl.hpp.

## Kernel() [2/4]

cl::Kernel::Kernel | ( | const Program & | program,
|  | const char * | name,
|  | cl_int * | err = nullptr )

inline

Definition at line 7514 of file opencl.hpp.

## Kernel() [3/4]

cl::Kernel::Kernel | ( |  | ) |

inline

Default constructor - initializes to nullptr.

Definition at line 6265 of file opencl.hpp.

## Kernel() [4/4]

cl::Kernel::Kernel | ( | const cl_kernel & | kernel,
|  | bool | retainObject = false )

inline explicit

Constructor from cl_kernel - takes ownership.

Parameters

  retainObject | will cause the constructor to retain its cl object. Defaults to false to maintain compatibility with earlier versions. This effectively transfers ownership of a refcount on the cl_kernel into the new Kernel object.

Definition at line 6275 of file opencl.hpp.

## Member Function Documentation

## clone()

Kernel cl::Kernel::clone | ( |  | ) |

inline

Make a deep copy of the kernel object including its arguments.

Returns
  A new kernel object with internal state entirely separate from that of the original but with any arguments set on the original intact.

Definition at line 6569 of file opencl.hpp.

## enableFineGrainedSystemSVM()

cl_int cl::Kernel::enableFineGrainedSystemSVM | ( | bool | svmEnabled | ) |

inline

Enable fine-grained system SVM.

Note
  It is only possible to enable fine-grained system SVM if all devices in the context associated with kernel support it.

Parameters

  svmEnabled | True if fine-grained system SVM is requested. False otherwise.

Returns
  CL_SUCCESS if the function was executed succesfully. CL_INVALID_OPERATION if no devices in the context support fine-grained system SVM.

## operator=()

Kernel & cl::Kernel::operator= | ( | const cl_kernel & | rhs | ) |
