.LP
The <\fBarpa/inet.h\fR> header defines the type \fBin_port_t\fR, the type \fBin_addr_t\fR, and the \fBin_addr\fR structure, as described in \fBin.h\fR(3HEAD).

in_addr_t       inet_addr(const char *);
in_addr_t       inet_lnaof(struct in_addr);
struct in_addr  inet_makeaddr(in_addr_t, in_addr_t);
in_addr_t       inet_netof(struct in_addr);
in_addr_t       inet_network(const char *);
char            *inet_ntoa(struct in_addr);
