byteorder(3SOCKET)					     Sockets Library Functions						byteorder(3SOCKET)

NAME

       byteorder, htonl, htonll, htons, ntohl, ntohll, ntohs - convert values between host and network byte order

SYNOPSIS

       cc [ flag... ] file... -lsocket	-lnsl  [ library... ]
       #include <sys/types.h>
       #include <netinet/in.h>
       #include <inttypes.h>

       uint32_t htonl(uint32_t hostlong);

       uint64_t htonll(uint64_t hostlonglong);

       uint16_t htons(uint16_t hostshort);

       uint32_t ntohl(uint32_t netlong);

       uint64_t ntonll(uint64_t hostlonglong);

       uint16_t ntohs(uint16_t netshort);

DESCRIPTION

       These  functions  convert 16-bit, 32-bit, and 64-bit quantities between network byte order and host byte order. On some architectures these
       routines are defined as NULL macros in the include file <netinet/in.h>. On other architectures, the routines are functional when  the  host
       byte order is different from network byte order.

       These  functions  are  most  often  used in conjunction with Internet addresses and ports as returned by gethostent() and getservent(). See
       gethostbyname(3NSL) and getservbyname(3SOCKET).
