преобразовывать значения между порядком байтов хоста и сети (convert values between host and network byte order)
Имя (Name)
htonl, htons, ntohl, ntohs - convert values between host and
network byte order
Синопсис (Synopsis)
#include <arpa/inet.h>
uint32_t htonl(uint32_t hostlong);
uint16_t htons(uint16_t hostshort);
uint32_t ntohl(uint32_t netlong);
uint16_t ntohs(uint16_t netshort);
Описание (Description)
The htonl() function converts the unsigned integer hostlong from
host byte order to network byte order.
The htons() function converts the unsigned short integer
hostshort from host byte order to network byte order.
The ntohl() function converts the unsigned integer netlong from
network byte order to host byte order.
The ntohs() function converts the unsigned short integer netshort
from network byte order to host byte order.
On the i386 the host byte order is Least Significant Byte first,
whereas the network byte order, as used on the Internet, is Most
Significant Byte first.
