Mapping network names (Internet domain)

Routines are provided for mapping network names to


numbers, and mapping numbers to network names. These routines return a netent structure. The network number is limited to 32 bits.

struct	netent {
        char                *n_name;
        char               **n_aliases;
        int                  n_addrtype;
        unsigned long        n_net;
        }

*n_name

is the official name of net.

**n_aliases

is the alias list.

n_addrtype

is the net address type.

n_net

is the network number (32-bit limit).
