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(5)), 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(5)), 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);
