Function nvml_binding::bindings::nvmlDeviceGetMemoryInfo

pub unsafe extern "C" fn nvmlDeviceGetMemoryInfo(
    device: nvmlDevice_t, 
    memory: *mut nvmlMemory_t
) -> nvmlReturn_t

Retrieves the amount of used, free and total memory available on the device, in bytes.

For all products.

Enabling ECC reduces the amount of total available memory, due to the extra required parity bits. Under WDDM most device memory is allocated and managed on startup by Windows.

Under Linux and Windows TCC, the reported amount of used memory is equal to the sum of memory allocated by all active channels on the device.

See \ref nvmlMemory_t for details on available memory info.

@param device The identifier of the target device @param memory Reference in which to return the memory information

@return - \ref NVML_SUCCESS if \a memory has been populated - \ref NVML_ERROR_UNINITIALIZED if the library has not been successfully initialized - \ref NVML_ERROR_INVALID_ARGUMENT if \a device is invalid or \a memory is NULL - \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
