Detailed Description

Routing Utility Functions.

1) Translating Routing Table Names

// libnl is only aware of the de facto standard routing table names.
// Additional name <-> identifier associations have to be read in via
// a configuration file, f.e. /etc/iproute2/rt_tables
err = rtnl_route_read_table_names("/etc/iproute2/rt_tables");
 
// Translating a table name to its idenfier
int table = rtnl_route_str2table("main");
 
// ... and the other way around.
char buf[32];
printf("Name: %s\n",
       rtnl_route_table2str(table, buf, sizeof(buf)));
