SYNOPSIS
#include <arpa/inet.h>
char *inet_net_pton(int af, const char *src, void *dst, size_t size);
DESCRIPTION
The
With CIDR, a single IP address can be used to designate many unique IP addresses. A CIDR IP address looks like a normal IP address except that it ends with a slash followed by a number, called the IP prefix. For example:
172.200.0.0/16
The IP prefix specifies how many addresses are covered by the CIDR address, with lower numbers covering more addresses. An IP prefix of /12, for example, can be used to address 4,096 former Class C addresses.
PARAMETERS
- af
-
Specifies the address family. Currently, only AF_INET is supported.
- src
-
Points to the presentation-format address. The format of the address is interpreted according to af.
- dst
-
Points to the buffer where the converted address is stored.
- size
-
Is the size of dst, in bytes.
RETURN VALUES
On success, the
- EAFNOSUPPORT
-
The address family specified in af is not supported by this function.
- EMSGSIZE
-
The buffer specified by dst and size is not large enough to contain the converted address.
- ENOENT
-
The address could not be parsed.
