ACE_INET_Addr::ACE_INET_Addr | ( | void |  | ) |

| Default constructor.

ACE_INET_Addr::ACE_INET_Addr | ( | const ACE_INET_Addr & |  | ) |

| Copy constructor.

ACE_INET_Addr::ACE_INET_Addr | ( | const sockaddr_in * | ,
|  | int | len
| ) |

| Creates an ACE_INET_Addr from a sockaddr_in structure.

ACE_INET_Addr::ACE_INET_Addr | ( | u_short | port_number,
|  | const char | host_name[],
|  | int | address_family = `AF_UNSPEC`
| ) |

| Creates an ACE_INET_Addr from a <port_number> and the remote <host_name>. The port number is assumed to be in host byte order. To set a port already in network byte order, please See also: set(). Use address_family to select IPv6 (PF_INET6) vs. IPv4 (PF_INET).

ACE_INET_Addr::ACE_INET_Addr | ( | const char | address[] | ) | `[explicit]`

| Initializes an ACE_INET_Addr from the <address>, which can be "ip-number:port-number" (e.g., "tango.cs.wustl.edu:1234" or "128.252.166.57:1234"). If there is no ':' in the <address> it is assumed to be a port number, with the IP address being INADDR_ANY.

ACE_INET_Addr::ACE_INET_Addr | ( | u_short | port_number,
|  | ACE_UINT32 | ip_addr = `INADDR_ANY`
| ) | `[explicit]`

| Creates an ACE_INET_Addr from a <port_number> and an Internet <ip_addr>. This method assumes that <port_number> and <ip_addr> are in host byte order. If you have addressing information in network byte order, See also: set().

ACE_INET_Addr::ACE_INET_Addr | ( | const char | port_name[],
|  | const char | host_name[],
|  | const char | protocol[] = `"tcp"`
| ) |

| Uses <getservbyname> to create an ACE_INET_Addr from a <port_name>, the remote <host_name>, and the <protocol>.

ACE_INET_Addr::ACE_INET_Addr | ( | const char | port_name[],
|  | ACE_UINT32 | ip_addr,
|  | const char | protocol[] = `"tcp"`
| ) |

| Uses <getservbyname> to create an ACE_INET_Addr from a <port_name>, an Internet <ip_addr>, and the <protocol>. This method assumes that <ip_addr> is in host byte order.

|  | const wchar_t | host_name[],
|  | int | address_family = `AF_UNSPEC`
| ) |

ACE_INET_Addr::ACE_INET_Addr | ( | const wchar_t | address[] | ) | `[explicit]`

ACE_INET_Addr::ACE_INET_Addr | ( | const wchar_t | port_name[],
|  | const wchar_t | host_name[],
|  | const wchar_t | protocol[] = `ACE_TEXT_WIDE("tcp")`
| ) |

ACE_INET_Addr::ACE_INET_Addr | ( | const wchar_t | port_name[],
|  | ACE_UINT32 | ip_addr,

## Member Function Documentation

ACE_BEGIN_VERSIONED_NAMESPACE_DECL int ACE_INET_Addr::addr_to_string | ( | ACE_TCHAR | buffer[],
|  | size_t | size,
|  | int | ipaddr_format = `1`
| ) | const`[virtual]`

| Transform the current ACE_INET_Addr address into string format. If <ipaddr_format> is non-0 this produces "ip-number:port-number" (e.g., "128.252.166.57:1234"), whereas if <ipaddr_format> is 0 this produces "ip-name:port-number" (e.g., "tango.cs.wustl.edu:1234"). Returns -1 if the <size> of the <buffer> is too small, else 0.

ACE_INLINE int ACE_INET_Addr::determine_type | ( | void |  | ) | const`[private]`

| ) | const

int ACE_INET_Addr::get_host_name | ( | char | hostname[],
|  | size_t | hostnamelen
| ) | const

| Return the character representation of the name of the host, storing it in the <hostname> (which is assumed to be <hostnamelen> bytes long). This version is reentrant. If <hostnamelen> is greater than 0 then <hostname> will be NUL-terminated even if -1 is returned.

int ACE_INET_Addr::get_host_name_i | ( | char | hostname[],
|  | size_t | hostnamelen
| ) | const`[private]`

| Insure that hostname is properly null-terminated.

| Compare two addresses for inequality.

ACE_INLINE bool ACE_INET_Addr::operator< | ( | const ACE_INET_Addr & | rhs | ) | const

| Returns `true` if `this` is less than rhs. In this context, "less than" is defined in terms of IP address and TCP port number. This operator makes it possible to use `ACE_INET_Addrs` in STL maps.

bool ACE_INET_Addr::operator== | ( | const ACE_INET_Addr & | SAP | ) | const

| Compare two addresses for equality. The addresses are considered equal if they contain the same IP address and port number.

|  | ACE_UINT32 | ip_addr,
|  | const wchar_t | protocol[] = `ACE_TEXT_WIDE("tcp")`
| ) |

ACE_INLINE int ACE_INET_Addr::set | ( | const wchar_t | port_name[],
|  | const wchar_t | host_name[],
|  | const wchar_t | protocol[] = `ACE_TEXT_WIDE("tcp")`
| ) |

ACE_INLINE int ACE_INET_Addr::set | ( | u_short | port_number,

|  | int | address_family = `AF_UNSPEC`
| ) |

int ACE_INET_Addr::set | ( | const sockaddr_in * | ,
|  | int | len
| ) |

| Creates an ACE_INET_Addr from a sockaddr_in structure.

int ACE_INET_Addr::set | ( | const char | addr[] | ) |

| Initializes an ACE_INET_Addr from the <addr>, which can be "ip-number:port-number" (e.g., "tango.cs.wustl.edu:1234" or "128.252.166.57:1234"). If there is no ':' in the <address> it is assumed to be a port number, with the IP address being INADDR_ANY.

int ACE_INET_Addr::set | ( | const char | port_name[],
|  | ACE_UINT32 | ip_addr,
|  | const char | protocol[] = `"tcp"`
| ) |

| Uses <getservbyname> to initialize an ACE_INET_Addr from a <port_name>, an <ip_addr>, and the <protocol>. This assumes that <ip_addr> is already in network byte order.

int ACE_INET_Addr::set | ( | const char | port_name[],
|  | const char | host_name[],
|  | const char | protocol[] = `"tcp"`
| ) |

| Uses <getservbyname> to initialize an ACE_INET_Addr from a <port_name>, the remote <host_name>, and the <protocol>.

int ACE_INET_Addr::set | ( | u_short | port_number,
|  | ACE_UINT32 | ip_addr = `INADDR_ANY`,
|  | int | encode = `1`,
|  | int | map = `0`
| ) |

| Initializes an ACE_INET_Addr from a port_number and an Internet ip_addr. If encode is non-zero then the port number and IP address are converted into network byte order, otherwise they are assumed to be in network byte order already and are passed straight through. If <map> is non-zero and IPv6 support has been compiled in, then this address will be set to the IPv4-mapped IPv6 address of it.

int ACE_INET_Addr::set | ( | u_short | port_number,
|  | const char | host_name[],
|  | int | encode = `1`,
|  | int | address_family = `AF_UNSPEC`
| ) |

| Initializes an ACE_INET_Addr from a <port_number> and the remote <host_name>. If <encode> is non-zero then <port_number> is converted into network byte order, otherwise it is assumed to be in network byte order already and are passed straight through. address_family can be used to select IPv4/IPv6 if the OS has IPv6 capability (ACE_HAS_IPV6 is defined). To specify IPv6, use the value AF_INET6. To specify IPv4, use AF_INET.

int ACE_INET_Addr::set | ( | const ACE_INET_Addr & |  | ) |

| Initializes from another ACE_INET_Addr.

void ACE_INET_Addr::set_addr | ( | void * | ,
|  | int | len,

| ) | `[virtual]`

| Set a pointer to the address.

void ACE_INET_Addr::set_addr | ( | void * | ,
|  | int | len
| ) | `[virtual]`

| Set a pointer to the address. Reimplemented from ACE_Addr.

int ACE_INET_Addr::set_address | ( | const char * | ip_addr,
|  | int | len,
|  | int | encode = `1`,
|  | int | map = `0`
| ) |

| Sets the address without affecting the port number. If <encode> is enabled then <ip_addr> is converted into network byte order, otherwise it is assumed to be in network byte order already and are passed straight through. The size of the address is specified in the <len> parameter. If <map> is non-zero, IPv6 support has been compiled in, and <ip_addr> is an IPv4 address, then this address is set to the IPv4-mapped IPv6 address of it.

int ACE_INET_Addr::set_interface | ( | const char * | intf_name | ) |

| Sets the interface that should be used for this address. This only has an effect when the address is link local, otherwise it does nothing.

void ACE_INET_Addr::set_port_number | ( | u_short | ,
|  | int | encode = `1`
| ) |

| Sets the port number without affecting the host name. If <encode> is enabled then <port_number> is converted into network byte order, otherwise it is assumed to be in network byte order already and are passed straight through. Reimplemented in ACE_Multihomed_INET_Addr.

int ACE_INET_Addr::string_to_addr | ( | const char | address[] | ) | `[virtual]`

| Initializes an ACE_INET_Addr from the address, which can be "ip-addr:port-number" (e.g., "tango.cs.wustl.edu:1234"), "ip-addr:port-name" (e.g., "tango.cs.wustl.edu:telnet"), "ip-number:port-number" (e.g., "128.252.166.57:1234"), or "ip-number:port-name" (e.g., "128.252.166.57:telnet"). If there is no ':' in the <address> it is assumed to be a port number, with the IP address being INADDR_ANY.
