Notes
Increments the device reference count if
device is a valid sub-device created by a call to
clCreateSubDevices.
If device is a root level device i.e. a cl_device_id
returned by clGetDeviceIDs,
the device reference count remains unchanged.
Errors
Returns CL_SUCCESS if the function is executed successfully or the device is a root-level device. Otherwise, it returns one of the following errors:
- CL_INVALID_DEVICE if
deviceis not a valid sub-device created by a call to clCreateSubDevices. - 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.
