Function

Description

htonl (uint32_t n)

uint32_t

Converts an integer from the host byte order to the network byte order.

htons (uint16_t n)

uint16_t

Converts a 16-bit integer from the host byte order to the network byte order.

ntohl (uint32_t n)

uint32_t

Converts an integer from the network byte order to the host byte order.

ntohs (uint16_t n)

uint16_t

Converts a 16-bit integer from the network byte order to the host byte order.

inet_addr (const char *p)

in_addr_t

Converts a string from the IPv4 numbers-and-dots notation to the binary data in network byte order.

inet_network (const char *p)

in_addr_t

Converts a string from the IPv4 numbers-and-dots notation to the binary data in host byte order.

inet_ntoa (struct in_addr in)

char *

Converts a network address to a string in dotted-decimal format.

inet_pton (int af, const char *__restrict s, void *__restrict a0)

int

Converts a string to a network address in the specified address family.

inet_ntop (int af, const void *restrict a0, char *restrict s, socklen_t l)

const char *

Converts a network address in the specified address family to a string.

inet_aton (const char *s0, struct in_addr *dest)

int

Converts an IP address from the string format to the 32-bit binary format in network byte order.

inet_makeaddr (in_addr_t n, in_addr_t h)

struct in_addr

Converts the network number and host address to the network address.

inet_lnaof (struct in_addr in)

in_addr_t

Converts an IP address into a host ID in host byte order without network bits.

inet_netof (struct in_addr in)

in_addr_t

Extracts the network number from the in_addr structure and converts it to the host byte order.
