Member Function Documentation

CArchSocket CArchNetworkBSD::acceptSocket CArchSocket  s,
CArchNetAddress addr
[virtual]
 

Accept connection on socket.

Accepts a connection on socket s, returning a new socket for the connection and filling in addr with the address of the remote end. addr may be NULL if the remote address isn't required. The original socket s is unaffected and remains in the listening state. The new socket shares most of the properties of s except it's not in the listening state and it's connected. Returns NULL if there are no pending connection requests.

Implements IArchNetwork.

void CArchNetworkBSD::bindSocket CArchSocket  s,
CArchNetAddress  addr
[virtual]
 

Bind socket to address.

Binds socket s to the address addr.

Implements IArchNetwork.

References CArchNetAddressImpl::m_addr, CArchSocketImpl::m_fd, and CArchNetAddressImpl::m_len.

void CArchNetworkBSD::closeSocket CArchSocket  s  )  [virtual]
 

Release a socket reference.

Deletes the given socket object. This does not destroy the socket the object referred to until there are no remaining references for the socket.

Implements IArchNetwork.

References CArchSocketImpl::m_fd, and CArchSocketImpl::m_refCount.

void CArchNetworkBSD::closeSocketForRead CArchSocket  s  )  [virtual]
 

Close socket for further reads.

Calling this disallows future reads on socket s.

Implements IArchNetwork.

Definition at line 154 of file CArchNetworkBSD.cpp.

References CArchSocketImpl::m_fd.

void CArchNetworkBSD::closeSocketForWrite CArchSocket  s  )  [virtual]
 

Close socket for further writes.

Calling this disallows future writes on socket s.

Implements IArchNetwork.

Definition at line 166 of file CArchNetworkBSD.cpp.

References CArchSocketImpl::m_fd.

bool CArchNetworkBSD::connectSocket CArchSocket  s,
CArchNetAddress  name
[virtual]
 

Connect socket.

Connects the socket s to the remote address addr. Returns true if the connection succeed immediately, false if the connection is in progress, and throws if the connection failed immediately. If it returns false, pollSocket() can be used to wait on the socket for writing to detect when the connection finally succeeds or fails.

Implements IArchNetwork.

References CArchNetAddressImpl::m_addr, CArchSocketImpl::m_fd, and CArchNetAddressImpl::m_len.

CArchSocket CArchNetworkBSD::copySocket CArchSocket  s  )  [virtual]
 

Copy a socket object.

Returns a reference to to socket referred to by s.

Implements IArchNetwork.

Definition at line 118 of file CArchNetworkBSD.cpp.

References CArchSocketImpl::m_refCount.

bool CArchNetworkBSD::isAnyAddr CArchNetAddress   )  [virtual]
 

Test for the "any" address.

Returns true if addr is the "any" address. newAnyAddr() returns an "any" address.

Implements IArchNetwork.

Definition at line 819 of file CArchNetworkBSD.cpp.

References getAddrFamily(), CArchNetAddressImpl::m_addr, and CArchNetAddressImpl::m_len.

void CArchNetworkBSD::listenOnSocket CArchSocket  s  )  [virtual]
 

Listen for connections on socket.

Causes the socket s to begin listening for incoming connections.

Implements IArchNetwork.

Definition at line 189 of file CArchNetworkBSD.cpp.

References CArchSocketImpl::m_fd.

CArchSocket CArchNetworkBSD::newSocket EAddressFamily  ,
ESocketType 
[virtual]
 

Create a new socket.

The socket is an opaque data type.

Implements IArchNetwork.

int CArchNetworkBSD::pollSocket CPollEntry  [],
int  num,
double  timeout
[virtual]
 

Check socket state.

Tests the state of num sockets for readability and/or writability. Waits up to timeout seconds for some socket to become readable and/or writable (or indefinitely if timeout < 0). Returns the number of sockets that were readable (if readability was being queried) or writable (if writablility was being queried) and sets the m_revents members of the entries. kPOLLERR and kPOLLNVAL are set in m_revents as appropriate. If a socket indicates kPOLLERR then throwErrorOnSocket() can be used to determine the type of error. Returns 0 immediately regardless of the timeout if no valid sockets are selected for testing.

size_t CArchNetworkBSD::readSocket CArchSocket  s,
void *  buf,
size_t  len
[virtual]
 

Read data from socket.

Read up to len bytes from socket s in buf and return the number of bytes read. The number of bytes can be less than len if not enough data is available. Returns 0 if the remote end has disconnected and/or there is no more queued received data.

Implements IArchNetwork.

bool CArchNetworkBSD::setNoDelayOnSocket CArchSocket  ,
bool  noDelay
[virtual]
 

Turn Nagle algorithm on or off on socket.

Set socket to send messages immediately (true) or to collect small messages into one packet (false). Returns the previous state.

Implements IArchNetwork.

Definition at line 570 of file CArchNetworkBSD.cpp.

References CArchSocketImpl::m_fd.

bool CArchNetworkBSD::setReuseAddrOnSocket CArchSocket  ,
bool  reuse
[virtual]
 

Turn address reuse on or off on socket.

Allows the address this socket is bound to to be reused while in the TIME_WAIT state. Returns the previous state.

Implements IArchNetwork.

Definition at line 593 of file CArchNetworkBSD.cpp.

References CArchSocketImpl::m_fd.

void CArchNetworkBSD::throwErrorOnSocket CArchSocket   )  [virtual]
 

Check error on socket.

If the socket s is in an error state then throws an appropriate XArchNetwork exception.

Implements IArchNetwork.

Definition at line 531 of file CArchNetworkBSD.cpp.

References CArchSocketImpl::m_fd.

void CArchNetworkBSD::unblockPollSocket CArchThread  thread  )  [virtual]
 

Unblock thread in pollSocket().

Cause a thread that's in a pollSocket() call to return. This call may return before the thread is unblocked. If the thread is not in a pollSocket() call this call has no effect.

Implements IArchNetwork.

Definition at line 489 of file CArchNetworkBSD.cpp.

size_t CArchNetworkBSD::writeSocket CArchSocket  s,
const void *  buf,
size_t  len
[virtual]
 

Write data from socket.

Write up to len bytes to socket s from buf and return the number of bytes written. The number of bytes can be less than len if the remote end disconnected or the internal buffers fill up.

Implements IArchNetwork.
