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 ref-
       erence 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);
