Description

ne_iaddr_make creates an ne_inet_addr object from a raw binary network address; for instance the four bytes 0x7f 0x00 0x00 0x01 represent the IPv4 address 127.0.0.1. The object returned is suitable for passing to ne_sock_connect. A binary IPv4 address contains four bytes; a binary IPv6 address contains sixteen bytes; addresses passed must be in network byte order.

ne_iaddr_cmp can be used to compare two network addresses; returning zero only if they are identical. The addresses need not be of the same address type; if the addresses are not of the same type, the return value is guaranteed to be non-zero.

ne_iaddr_print can be used to print the human-readable string representation of a network address into a buffer, for instance the string "127.0.0.1".

ne_iaddr_free releases the memory associated with a network address object.

Return value

ne_iaddr_make returns NULL if the address type passed is not supported (for instance on a platform which does not support IPv6).

ne_iaddr_print returns the buffer pointer, and never NULL.

Examples

The following example connects a socket to port 80 at the address 127.0.0.1.

unsigned char addr[] = "\0x7f\0x00\0x00\0x01";
ne_inet_addr *ia;

ia = ne_iaddr_make(ne_iaddr_ipv4, addr);
if (ia != NULL) {
    ne_socket *sock = ne_sock_connect(ia, 80);
    ne_iaddr_free(ia);
    /* ... */
} else {
    /* ... */
}
