inet_makeaddr(3) Library Functions Manual inet_makeaddr(3)NAME
inet_makeaddr - Translates an Internet network address and host address into an Internet network byte-ordered address
LIBRARY
Standard C Library (libc.so, libc.a)
SYNOPSIS
#include <arpa/inet.h>
struct in_addr inet_makeaddr( in_addr_t net_num, in_addr_t loc_addr) ;
STANDARDS
Interfaces documented on this reference page conform to industry standards as follows:
inet_makeaddr(): XNS4.0
Refer to the standards(5) reference page for more information about industry standards and associated tags.
PARAMETERS
Defines a network number in host-byte order. Defines a host (local) address in host-byte order.
DESCRIPTION
The inet_makeaddr() function translates a network number and a local host address into their equivalent Internet address. The Internet
address is returned in network-byte order.
RETURN VALUES
The inet_makeaddr() function returns an Internet address in network byte order.
ERRORS
Current industry standards for inet_makeaddr() do not define error values.

inet_addr(3) Library Functions Manual inet_addr(3)NAME
inet_addr - Translates an Internet network address string to an Internet address integer
LIBRARY
Standard C Library (libc.so, libc.a)
SYNOPSIS
#include <arpa/inet.h>
in_addr_t inet_addr( const char *string) ;
STANDARDS
Interfaces documented on this reference page conform to industry standards as follows:
inet_addr(): 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 character string of the form a.b.c.d, where a, b, c, and d may be expressed as decimal, octal,
or hexadecimal integers in the C idiom.
DESCRIPTION
The inet_addr() function translates a dot-formatted Internet character address string to an Internet address integer. The Internet address
integer is returned as a network byte-ordered integer.
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.
NOTES
The dot-formatted network-address a.b.c.d is returned as the machine integer dcba.
RETURN VALUES
Upon successful completion, the inet_addr() function returns an equivalent network byte-ordered address integer. Otherwise, it returns
(in_addr_t)-1.
ERRORS
Current industry standards for inet_addr() do not define error values.
