Data Structures
struct	GNUNET_BANDWIDTH_Value32NBO
	32-bit bandwidth used for network exchange by GNUnet, in bytes per second. More...

struct	GNUNET_BANDWIDTH_Tracker
	Struct to track available bandwidth. More...

Macros
#define	GNUNET_BANDWIDTH_ZERO GNUNET_BANDWIDTH_value_init (0)
	Convenience definition to use for 0-bandwidth.

#define	GNUNET_BANDWIDTH_VALUE_MAX GNUNET_BANDWIDTH_value_init (UINT32_MAX)
	Maximum possible bandwidth value.

Typedefs
typedef void(*	GNUNET_BANDWIDTH_TrackerUpdateCallback) (void *cls)
	Callback to be called by the bandwidth tracker if the tracker was updated and the client should update it's delay values.

typedef void(*	GNUNET_BANDWIDTH_ExcessNotificationCallback) (void *cls)
	Callback to be called by the bandwidth tracker if the tracker was updated and the client should update it's delay values.

Functions
struct GNUNET_BANDWIDTH_Value32NBO	GNUNET_BANDWIDTH_value_init (uint32_t bytes_per_second)
	Create a new bandwidth value.

uint64_t	GNUNET_BANDWIDTH_value_get_available_until (struct GNUNET_BANDWIDTH_Value32NBO bps, struct GNUNET_TIME_Relative deadline)

struct GNUNET_TIME_Relative	GNUNET_BANDWIDTH_value_get_delay_for (struct GNUNET_BANDWIDTH_Value32NBO bps, uint64_t size)
	At the given bandwidth, calculate how long it would take for 'size' bytes to be transmitted.

void	GNUNET_BANDWIDTH_tracker_notification_stop (struct GNUNET_BANDWIDTH_Tracker *av)
	Stop notifying about tracker updates and excess notifications.

int	GNUNET_BANDWIDTH_tracker_consume (struct GNUNET_BANDWIDTH_Tracker *av, ssize_t size)
