Function nvml_binding::bindings::nvmlDeviceGetBoardId

pub unsafe extern "C" fn nvmlDeviceGetBoardId(
    device: nvmlDevice_t, 
    boardId: *mut c_uint
) -> nvmlReturn_t

Retrieves the device boardId from 0-N. Devices with the same boardId indicate GPUs connected to the same PLX. Use in conjunction with \ref nvmlDeviceGetMultiGpuBoard() to decide if they are on the same board as well. The boardId returned is a unique ID for the current configuration. Uniqueness and ordering across reboots and system configurations is not guaranteed (i.e. if a Tesla K40c returns 0x100 and the two GPUs on a Tesla K10 in the same system returns 0x200 it is not guaranteed they will always return those values but they will always be different from each other).

For Fermi &tm; or newer fully supported devices.

@param device The identifier of the target device @param boardId Reference in which to return the device's board ID

@return - \ref NVML_SUCCESS if \a boardId has been set - \ref NVML_ERROR_UNINITIALIZED if the library has not been successfully initialized - \ref NVML_ERROR_INVALID_ARGUMENT if \a device is invalid or \a boardId is NULL - \ref NVML_ERROR_NOT_SUPPORTED if the device does not support this feature - \ref NVML_ERROR_GPU_IS_LOST if the target GPU has fallen off the bus or is otherwise inaccessible - \ref NVML_ERROR_UNKNOWN on any unexpected error
