## Member Function Documentation

QString KSocketAddress::pretty | ( |  | ) | const`[virtual]`

Returns a string representation of this socket.

Returns:
  a pretty string representation

Reimplemented in KInetSocketAddress, and KUnixSocketAddress.

Definition at line 110 of file ksockaddr.cpp.

const sockaddr* KSocketAddress::address | ( |  | ) | const`[inline]`

Returns a sockaddr structure, for passing down to library functions.

Returns:
  the sockaddr structure, can be 0

Reimplemented in KUnixSocketAddress.

Definition at line 78 of file ksockaddr.h.

Referenced by KNetwork::KInetSocketAddress::operator const sockaddr_in *(), KNetwork::KInetSocketAddress::operator const sockaddr_in6 *(), KNetwork::KUnixSocketAddress::operator const sockaddr_un *(), and KUnixSocketAddress::operator const sockaddr_un *().

virtual ksocklen_t KSocketAddress::size | ( |  | ) | const`[inline, virtual]`

Returns sockaddr structure size.

Returns:
  the size of the sockaddr structre, 0 if there is none.

Reimplemented in KInetSocketAddress.

Definition at line 85 of file ksockaddr.h.

KSocketAddress::operator const sockaddr * | ( |  | ) | const`[inline]`

Returns a sockaddr structure, for passing down to library functions.

Returns:
  the sockaddr structure, can be 0.

See also:
  address()

Definition at line 93 of file ksockaddr.h.

int KSocketAddress::family | ( |  | ) | const

Returns the family of this address.

Returns:
  the family of this address, AF_UNSPEC if it's undefined

Definition at line 115 of file ksockaddr.cpp.

Referenced by isCoreEqual(), and isEqual().

int KSocketAddress::ianaFamily | ( |  | ) | const`[inline]`

Returns the IANA family number of this address.

Returns:
  the IANA family number of this address (1 for AF_INET. 2 for AF_INET6, otherwise 0)

Definition at line 107 of file ksockaddr.h.

bool KSocketAddress::isEqual | ( | const KSocketAddress & | other | ) | const`[virtual]`

Returns true if this equals the other socket.

Parameters:

  | other | the other socket

Returns:
  true if both sockets are equal

Definition at line 159 of file ksockaddr.cpp.

References KInetSocketAddress::areEqualInet(), KInetSocketAddress::areEqualInet6(), KUnixSocketAddress::areEqualUnix(), and family().

bool KSocketAddress::operator== | ( | const KSocketAddress & | other | ) | const`[inline]`

Overloaded == operator.

See also:
  isEqual()

Definition at line 123 of file ksockaddr.h.

bool KSocketAddress::isCoreEqual | ( | const KSocketAddress & | other | ) | const

Some sockets may differ in such things as services or port numbers, like Internet sockets.

This function compares only the core part of that, if possible.

If not possible, like the default implementation, this returns the same as isEqual.

Parameters:

  | other | the other socket

Returns:
  true if the code part is equal

Definition at line 179 of file ksockaddr.cpp.

References KInetSocketAddress::areEqualInet(), KInetSocketAddress::areEqualInet6(), KUnixSocketAddress::areEqualUnix(), and family().

bool KSocketAddress::isCoreEqual | ( | const KSocketAddress * | other | ) | const`[inline]`

Some sockets may differ in such things as services or port numbers, like Internet sockets.

This function compares only the core part of that, if possible.

If not possible, like the default implementation, this returns the same as isEqual.

Parameters:

  | other | the other socket

Returns:
  true if the code part is equal

Definition at line 148 of file ksockaddr.h.

QString KSocketAddress::nodeName | ( |  | ) | const`[virtual]`

Returns the node name of this socket, as KExtendedSocket::lookup expects as the first argument.

In the case of Internet sockets, this is the hostname. The default implementation returns QString::null.

Returns:
  the node name, can be QString::null

Reimplemented in KInetSocketAddress.

Definition at line 196 of file ksockaddr.cpp.

QString KSocketAddress::serviceName | ( |  | ) | const`[virtual]`

Returns the service name for this socket, as KExtendedSocket::lookup expects as the service argument.

In the case of Internet sockets, this is the port number. The default implementation returns QString::null.

Returns:
  the service name, can be QString::null

Reimplemented in KInetSocketAddress, and KUnixSocketAddress.

Definition at line 201 of file ksockaddr.cpp.

KSocketAddress * KSocketAddress::newAddress | ( | const struct sockaddr * | sa,
|  | ksocklen_t | size
| ) | `[static]`

Creates a new KSocketAddress or descendant class from given raw socket address.

Parameters:

  | sa | new socket address
  | size | new socket address's length

Returns:
  the new KSocketAddress, or 0 if the function failed

Definition at line 123 of file ksockaddr.cpp.

References KSocketAddress().

int KSocketAddress::ianaFamily | ( | int | af | ) | `[static]`

Returns the IANA family number of the given address family.

Returns 0 if there is no corresponding IANA family number.

Parameters:

  | af | the address family, in AF_* constants

Returns:
  the IANA family number of this address (1 for AF_INET. 2 for AF_INET6, otherwise 0)

Definition at line 206 of file ksockaddr.cpp.

int KSocketAddress::fromIanaFamily | ( | int | iana | ) | `[static]`

Returns the address family of the given IANA family number.

Returns:
  the address family, AF_UNSPEC for unknown IANA family numbers
