<para> |
| 37 |
The <function>sg_get_network_iface_stats</function> function |
| 38 |
takes a pointer to an int, <parameter>entries</parameter>, |
| 39 |
which is filled with the number of network interfaces the |
| 40 |
machine has. This is needed to know how many |
| 41 |
<structname>sg_network_iface_stats</structname> structures have |
| 42 |
been returned. A pointer is returned to the first |
| 43 |
<structname>sg_network_iface_stats</structname>. |
| 44 |
</para> |
| 45 |
<para> |
| 46 |
<function>sg_get_network_iface_stats</function> returns statistics |
| 47 |
about the network interfaces in the machine. Specifically, |
| 48 |
it returns the speed of the interface, the duplex state, and |
| 49 |
whether it is currently up. |
