inet_network(3) 					     Library Functions Manual						   inet_network(3)

NAME

       inet_network - Translates an Internet dot-formatted address string to a network address integer

LIBRARY

       Standard C Library (libc.so, libc.a)

SYNOPSIS

       #include <arpa/inet.h>
       in_addr_t inet_network(
	    const char *string );

STANDARDS

       Interfaces documented on this reference page conform to industry standards as follows:

       inet_network():	XNS4.0

       Refer to the standards(5) reference page for more information about industry standards and associated tags.

PARAMETERS

       Defines an Internet dot-formatted address as the character string a.b.c.d, where a, b, c and d may be expressed as decimal, octal, or hexa-
       decimal in the C-language idiom.

DESCRIPTION

       The inet_network() function translates a dot-formatted Internet network character address string to a network  byte-ordered  address  (most
       significant byte leftmost, least significant byte rightmost).

       Values specified using dot notation take on one of the following forms: When all four parts are specified, each is interpreted as a byte of
       data and assigned, from left to right, to the four bytes of an Internet address.  When three parts are specified, the last part	is  inter-
       preted as a 16-bit quantity and placed in the rightmost two bytes of the network address.  This format is convenient for specifying Class B
       network addresses as 128.net.host.  When two parts are specified, the last part is interpreted as a  24-bit  quantity  and  placed  in  the
       rightmost  three  bytes of the network address.	This format is convenient for specifying Class A network addresses as net.host.  When only
       one part is specified, the value is stored directly in the network address without any byte rearrangement.

       All numbers supplied as parts in dot notation can be decimal, octal, or hexadecimal, as specified in the ISO C standard. A leading 0x or 0X
       implies hexadecimal and a leading 0 implies octal.  Otherwise, the number is interpreted as decimal.

RETURN VALUES

       Upon successful completion, the inet_network() function returns an Internet byte-ordered address.  Otherwise, it returns (in_addr_t)-1.

ERRORS

       Current industry standards for inet_network() do not define error values.
