SYNOPSIS

9       #include <arpa/inet.h>

11

DESCRIPTION

13       The   <arpa/inet.h>   header  defines  the  type  in_port_t,  the  type
14       in_addr_t, and the in_addr structure, as described in in.h(3HEAD).
15
16
17       Inclusion of the <arpa/inet.h> header may also make visible all symbols
18       from in.h(3HEAD).
19
20
21       The  following  are  declared  as functions, and may also be defined as
22       macros:
23
24         in_addr_t       inet_addr(const char *);
25         in_addr_t       inet_lnaof(struct in_addr);
26         struct in_addr  inet_makeaddr(in_addr_t, in_addr_t);
27         in_addr_t       inet_netof(struct in_addr);
28         in_addr_t       inet_network(const char *);
29         char            *inet_ntoa(struct in_addr);
30
31
32   Default
33       For applications  that  do  not  require  standard-conforming  behavior
34       (those  that  use  the socket interfaces described in section 3N of the
35       reference manual; see Intro(3) and standards(5)), the following may  be
36       declared as functions, or defined as macros, or both:
37
38         uint32_t    htonl(uint32_t);
39         uint16_t    htons(uint16_t);
40         uint32_t    ntohl(uint32_t);
41         uint16_t    ntohs(uint16_t);
42
43
44   Standard conforming
45       For  applications that require standard-conforming behavior (those that
46       use the socket interfaces described in section  3XN  of  the  reference
47       manual;  see  Intro(3) and standards(5)), the following may be declared
48       as functions, or defined as macros, or both:
49
50         in_addr_t    htonl(in_addr_t);
51         in_port_t    htons(in_port_t);
52         in_addr_t    ntohl(in_addr_t);
53         in_port_t    ntohs(in_port_t);
