sg_get_network_iface_stats(3) get network interface statistics

SYNOPSIS


#include <statgrab.h>

sg_network_iface_stats *sg_get_network_iface_stats(int *entries);

DESCRIPTION

The sg_get_network_iface_stats function takes a pointer to an int, entries, which is filled with the number of network interfaces the machine has. This is needed to know how many sg_network_iface_stats structures have been returned. A pointer is returned to the first sg_network_iface_stats.

sg_get_network_iface_stats returns statistics about the network interfaces in the machine. Specifically, it returns the speed of the interface, the duplex state, and whether it is currently up.

RETURN VALUES

The sg_get_network_iface_stats returns a pointer to a structure of type sg_network_iface_stats. 

typedef enum{
        SG_IFACE_DUPLEX_FULL,
        SG_IFACE_DUPLEX_HALF,
        SG_IFACE_DUPLEX_UNKNOWN
}sg_iface_duplex;

Note: The SG_IFACE_DUPLEX_UNKNOWN value could mean that duplex hasn't been negotiated yet. 

typedef struct{
        char *interface_name;
        int speed;
        sg_iface_duplex duplex;
        int up;
}sg_network_iface_stats;
interface_name
The name known to the operating system. (eg. on linux it might be eth0)
speed
The speed of the interface, in megabits/sec.
duplex
The duplex state the interface is in. See sg_iface_duplex for permitted values.
up
Whether the interface is up.
