Defines
- #define NVML_DEVICE_PCI_BUS_ID_BUFFER_SIZE 16
-
Buffer size guaranteed to be large enough for pci bus id
- #define NVML_MAX_PHYSICAL_BRIDGE (128)
-
Maximum limit on Physical Bridges per Board
- #define NVML_VALUE_NOT_AVAILABLE (-1)
-
Special constant that some fields take when they are not available. Used when only part of the struct is not available.
Each structure explicitly states when to check for this value.
