INET.H(3HEAD) Headers INET.H(3HEAD)

NAME

inet.h, inet - definitions for internet operations

SYNOPSIS

#include <arpa/inet.h>

DESCRIPTION

The <arpa/inet.h> header defines the type in_port_t, the type
in_addr_t, and the in_addr structure, as described in in.h(3HEAD).

Inclusion of the <arpa/inet.h> header may also make visible all
symbols from in.h(3HEAD).

The following are declared as functions, and may also be defined as
macros:

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);

Default

For applications that do not require standard-conforming behavior
(those that use the socket interfaces described in section 3N of the
reference manual; see Intro(3) and standards(7)), the following may
be declared as functions, or defined as macros, or both:

uint32_t htonl(uint32_t);
uint16_t htons(uint16_t);
uint32_t ntohl(uint32_t);
uint16_t ntohs(uint16_t);

Standard conforming

For applications that require standard-conforming behavior (those
that use the socket interfaces described in section 3XN of the
reference manual; see Intro(3) and standards(7)), the following may
be declared as functions, or defined as macros, or both:

in_addr_t htonl(in_addr_t);
in_port_t htons(in_port_t);
in_addr_t ntohl(in_addr_t);
in_port_t ntohs(in_port_t);
