The inet_net_pton() function converts an Internet network number from presentation format — a printable form as held in a character string, such as, Internet standard dot notation, or Classless Internet Domain Routing (CIDR) — to network format (usually a struct in_addr or some other internal binary representation, in network byte order).
For more information on Internet addresses, see inet_net_ntop().
The number of bits that specify the network number (computed based on the class, or specified with /CIDR), or -1 if an error occurred (errno is set).
