This inspection searches for redundant class fields that can be replaced with local variables. If all local usages of a field are preceded by assignments to that field, the field can be removed and its usages replaced with local variables.

INET_PTON(3) Linux Programmer's Manual INET_PTON(3)
리눅스 프로그래머의 사용법
NAME
이름
inet_pton - convert IPv4 and IPv6 addresses from text to binary form
- IPv4 와 IPv6 주소들을 텍스트에서 바이너리 형태-폼?으로 변경한다.
SYNOPSIS
개요 - 뭐 이렇게 쓴다는 걸 알려줌. 아래 설명 잘 나옴...
#include <arpa/inet.h> //
int inet_pton(int af, const char *src, void *dst);
DESCRIPTION
설명
This function converts the character string src into a network address structure in the af address family,
then copies the network address structure to dst. The af argument must be either AF_INET or AF_INET6.
이 펑션은 문자열 src를 af 주소 집단의 네트워크 주소 구조체로 변경하고, 그 네트워크 주소 구조체를 dst에 복사한다. 그 af 함수 인자는 반드시 AF_INET 혹은 AF_INET6 중 하나이어야만 한다.
The following address families are currently supported:
아래의 주소 집단들이 현재 지원되고 있다: 2008년도인데????ㄷㄷㄷ
AF_INET
src points to a character string containing an IPv4 network address in dotted-decimal format,
"ddd.ddd.ddd.ddd", where ddd is a decimal number of up to three digits in the range 0 to 255. The
address is converted to a struct in_addr and copied to dst, which must be sizeof(struct in_addr) (4)
bytes (32 bits) long.
AF_INET6
src points to a character string containing an IPv6 network address. The address is converted to a
struct in6_addr and copied to dst, which must be sizeof(struct in6_addr) (16) bytes (128 bits) long.
The allowed formats for IPv6 addresses follow these rules:
1. The preferred format is x:x:x:x:x:x:x:x. This form consists of eight hexadecimal numbers, each
of which expresses a 16-bit value (i.e., each x can be up to 4 hex digits).
2. A series of contiguous zero values in the preferred format can be abbreviated to ::. Only one
instance of :: can occur in an address. For example, the loopback address 0:0:0:0:0:0:0:1 can be
abbreviated as ::1. The wildcard address, consisting of all zeros, can be written as ::.
3. An alternate format is useful for expressing IPv4-mapped IPv6 addresses. This form is written as
x:x:x:x:x:x:d.d.d.d, where the six leading xs are hexadecimal values that define the six most-
significant 16-bit pieces of the address (i.e., 96 bits), and the ds express a value in dotted-
decimal notation that defines the least significant 32 bits of the address. An example of such
an address is ::FFFF:204.152.189.116.
See RFC 2373 for further details on the representation of IPv6 addresses.
IPv6 주소들의 포현에 대한 더 자세함은 RFC2373을 참조하시라.
RETURN VALUE 이게 중요함 ㅋ
inet_pton() returns 1 on success (network address was successfully converted). 0 is returned if src does
not contain a character string representing a valid network address in the specified address family. If af
does not contain a valid address family, -1 is returned and errno is set to EAFNOSUPPORT.
뭐 성공하면 1, 0 일 경우는 올바른 주소를 전달해 줘, af가 이상한 값이면 -1
1 나오면 되겠다..
CONFORMING TO 아래를 따른다나..뽀직수
POSIX.1-2001.
NOTES : 노트 헉 그 노트 아님
Unlike inet_aton(3) and inet_addr(3), inet_pton() supports IPv6 addresses. On the other hand, inet_pton()
accepts only IPv4 addresses in dotted-decimal notation, whereas inet_aton(3) and inet_addr(3) allow the
more general numbers-and-dots notation (hexadecimal and octal number formats, and formats that don't
require all four bytes to be explicitly written). For an interface that handles both IPv6 addresses, and
IPv4 addresses in numbers-and-dots notation, see getaddrinfo(3).
어쨌든 얘는 특이하게 IPv6를 지원한다네, inet_aton과 inet_addr은 아닌가봐.
IPv6와 IPv4 수-점 표기하는 둘다 처리하는 인터페이스는 getaddrinfo를 봐.
BUGS : 뻐그들
AF_INET6 does not recognize IPv4 addresses. An explicit IPv4-mapped IPv6 address must be supplied in src instead.
EXAMPLE
The program below demonstrates the use of inet_pton() and inet_ntop(3). Here are some example runs:
$ ./a.out i6 0:0:0:0:0:0:0:0
::
$ ./a.out i6 1:0:0:0:0:0:0:8
1::8
$ ./a.out i6 0:0:0:0:0:FFFF:204.152.189.116
::ffff:204.152.189.116
