arpa_inet.h(0P)		   POSIX Programmer's Manual	       arpa_inet.h(0P)

       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
       implementation of this interface may differ (consult the	 corresponding
       Linux  manual page for details of Linux behavior), or the interface may
       not be implemented on Linux.

       arpa/inet.h — definitions for internet operations

       #include <arpa/inet.h>

       The <arpa/inet.h> header shall define the in_port_t and in_addr_t types
       as described in <netinet/in.h>.

       The   <arpa/inet.h>  header  shall  define  the	in_addr	 structure  as
       described in <netinet/in.h>.

       The  <arpa/inet.h>  header  shall  define   the	 INET_ADDRSTRLEN   and
       INET6_ADDRSTRLEN macros as described in <netinet/in.h>.

       The  following shall be declared as functions, or defined as macros, or
       both. If functions are declared, function prototypes shall be provided.

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

       The <arpa/inet.h> header shall define the uint32_t and  uint16_t	 types
       as described in <inttypes.h>.

       The following shall be declared as functions and may also be defined as
       macros. Function prototypes shall be provided.

	   in_addr_t	inet_addr(const char *);
	   char	       *inet_ntoa(struct in_addr);
	   const char  *inet_ntop(int, const void *restrict, char *restrict,
	   int		inet_pton(int, const char *restrict, void *restrict);

       Inclusion of the <arpa/inet.h> header may also make visible all symbols
       from <netinet/in.h> and <inttypes.h>.

       The following sections are informative.
