clGetDeviceInfo returns CL_SUCCESS if the function is executed successfully. Otherwise, it returns the
       following:

       •   CL_INVALID_DEVICE if device is not valid.

       •   CL_INVALID_VALUE if param_name is not one of the supported values or if size in bytes specified by
           param_value_size is less than size of return type as shown in the table above and param_value is not
           a NULL value or if param_name is a value that is available as an extension and the corresponding
           extension is not supported by the device.

       •   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.

device
           May be a device returned by clGetDeviceIDs(3clc) or a sub-device created by clCreateSubDevices(3clc).
           If device is a sub-device, the specific information for the sub-device will be returned. The
           information that can be queried using clGetDeviceInfo is specified in the table below.

       param_value
           A pointer to memory location where appropriate values for a given param_name as specified in the
           table below will be returned. If param_value is NULL, it is ignored.

       param_value_size
           Specifies the size in bytes of memory pointed to by param_value. This size in bytes must be ≥ size of
           return type specified in the table below.

       param_value_size_ret
           Returns the actual size in bytes of data being queried by param_value. If param_value_size_ret is
           NULL, it is ignored.

       param_name
           An enumeration constant that identifies the device information being queried. It can be one of the
           values as specified in the table below.
