Detailed Description
This object is used to hold the actual and valid internet address of a specific host machine that will be accessed through a socket.
- Author
- David Sugar dyfet.nosp@m.@ost.nosp@m.el.co.nosp@m.m Address of a specific Internet host machine.
Definition at line 561 of file address.h.
Constructor & Destructor Documentation
IPV4Host::IPV4Host
(
const char *
host = NULL )
Create a new host address for a specific internet host.
The internet host can be specified in a null terminated ASCII string and include either the physical host address or the DNS name of a host machine. Hence, an IPV4Host ("www.voxilla.org") can be directly declaired in this manner.
Defaults to the IP address that represents the interface matching "gethostname()".
- Parameters
-
host dns or physical address of an Internet host.
IPV4Host::IPV4Host
(
struct in_addr
addr )
Convert a system socket binary address such as may be returned through the accept() call or getsockpeer() into an internet host address object.
- Parameters
-
addr binary address of internet host.
Member Function Documentation
struct in_addr IPV4Address::getAddress
(
void
)
const
inherited
Provide a low level system usable struct in_addr object from the contents of IPV4Address.
This is needed for services such as bind() and connect().
- Returns
- system binary coded internet address.
struct in_addr IPV4Address::getAddress
(
size_t
i )
const
inherited
Provide a low level system usable struct in_addr object from the contents of IPV4Address.
This is needed for services such as bind() and connect().
- Parameters
-
i for IPV4Addresses with multiple addresses, returns the address at this index. User should call
getAddressCount() to determine the number of address the object contains.
- Returns
- system binary coded internet address. If parameter i is out of range, the first address is returned.
size_t IPV4Address::getAddressCount
(
)
const
inlineinherited
Returns the number of internet addresses that an IPV4Address object contains.
This usually only happens with IPV4Host objects where multiple IP addresses are returned for a DNS lookup
Definition at line 472 of file address.h.
const char* IPV4Address::getHostname
(
void
)
const
inherited
Provide a string representation of the value (Internet Address) held in the IPV4Address object.
- Returns
- string representation of IPV4Address.
bool IPV4Address::isInetAddress
(
void
)
const
inherited
May be used to verify if a given IPV4Address returned by another function contains a "valid" address, or "0.0.0.0" which is often used to mark "invalid" IPV4Address values.
- Returns
- true if address != 0.0.0.0.
bool IPV4Address::operator!
(
)
const
inlineinherited
Compare two internet addresses to see if they are not equal (if they each refer to unique and different physical ip addresses).
This is implimented in terms of operator==
Mask the internet host address object with a network mask address.
This is commonly used to coerce an address by subnet.
IPV4Address& IPV4Host::operator=
(
unsigned long
addr )
inline
Allows assignment from the return of functions like inet_addr() or htonl()
Definition at line 594 of file address.h.
bool IPV4Address::operator==
(
const
IPV4Address &
a )
const
Compare two internet addresses to see if they are equal (if they specify the physical address of the same internet host).
If there is more than one IP address in either IPV4Address object, this will return true if all of the IP addresses in the smaller are in the larger in any order.
void IPV4Address::setAddress
(
const char *
host )
protectedinherited
Used to specify a host name or numeric internet address.
- Parameters
-
host The string representation of the IP address or a hostname, , if NULL, it will default to INADDR_ANY
bool IPV4Address::setIPAddress
(
const char *
host )
protectedinherited
Sets the IP address from a string representation of the numeric address, ie "127.0.0.1".
- Parameters
-
host The string representation of the IP address
- Returns
- true if successful
