clReleaseDevice - Decrements the device reference count. cl_int clReleaseDevice(cl_device_id device);
Decrements the device reference count if device is a valid sub-device created by a call to clCreateSubDevices(3clc). If device is a root level device i.e. a cl_device_id returned by clGetDeviceIDs(3clc), the device reference count remains unchanged. After the device reference count becomes zero and all the objects attached to device (such as command-queues) are released, the device object is deleted.
Returns CL_SUCCESS if the function is executed successfully. Otherwise, it returns one of the following errors: · CL_INVALID_DEVICE if device is not a valid sub-device created by a call to clCreateSubDevices(3clc). · 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.
