Detailed Description

Base functionality for a TCP connected socket This class is pretty useless by itself but it does hide some of the platform differences from machine to machine.


Member Function Documentation

bool Active ( ) [inherited]

Ask if the socket is open (allocated)

bool ActiveOpen ( Socket_Address const  theaddress,
bool  setdelay 
)

This function will try and set the socket up for active open to a specified address and port provided by the input parameter.

bool ActiveOpenNonBlocking ( Socket_Address const  theaddress)

This function will try and set the socket up for active open to a specified address and port provided by the input parameter (non-blocking version)

Close ( ) [inherited]

closes a socket if it is open (allocated)

int DontLinger ( )

Turn off the linger flag.

The socket will quickly release buffered items and free up OS resources. You may lose a stream if you use this flag and do not negotiate the close at the application layer.

bool ErrorIsWouldBlocking ( int  err)
static TypeHandle getClassType ( ) [static]

Reimplemented from Socket_IP.

Reimplemented in Buffered_DatagramConnection.

static int GetLastError ( ) [static, inherited]

gets the last errcode from a socket operation

Socket_Address GetPeerName ( ) [inherited]

Wrapper on berkly getpeername...

int GetSocket ( ) [inherited]

Gets the base socket type.

int GetSocket ( ) [inherited]

Get The RAW file id of the socket.

TypeHandle getType ( ) [inherited]

Reimplemented in AnimChannelBase.

int getTypeIndex ( ) [inherited]

Returns the internal index number associated with this object's TypeHandle, a unique number for each different type.

This is equivalent to get_type().get_index().

static int InitNetworkDriver ( ) [static, inherited]
bool isExactType ( TypeHandle  handle) [inherited]

Returns true if the current object is the indicated type exactly.

bool isOfType ( TypeHandle  handle) [inherited]

Returns true if the current object is or derives from the indicated type.

string RecvData ( int  max_len)

Read the data from the connection.

Return type : int

  • if error 0 if socket closed for read or length is 0 + bytes read ( May be smaller than requested)
int SendData ( string  str)
int SetBlocking ( ) [inherited]

Set the socket to block on subsequent calls to socket functions that address this socket.

int SetLinger ( )

will control the behavior of SO_LINGER for a TCP socket

int SetLinger ( int  interval_seconds)

will control the behavior of SO_LINGER for a TCP socket

int SetNoDelay ( bool  flag)

Disable Nagle algorithm.

Don't delay send to coalesce packets

int SetNoDelay ( )

Disable Nagle algorithm.

Don't delay send to coalesce packets

int SetNonBlocking ( ) [inherited]

this function will throw a socket into non-blocking mode

int SetRecvBufferSize ( int  size) [inherited]

Ok it sets the recv buffer size for both tcp and UDP.

bool SetReuseAddress ( ) [inherited]

Informs a socket to reuse IP address as needed.

bool SetReuseAddress ( bool  flag) [inherited]

Informs a socket to reuse IP address as needed.

int SetSendBufferSize ( int  insize)

Just like it sounds.

Sets a buffered socket recv buffer size. This function does not refuse ranges outside hard-coded OS limits

SetSocket ( int  ins) [inherited]

Assigns an existing socket to this class.

bool ShutdownSend ( )
SocketIP ( ) [inherited]

Def Constructor.

SocketIP ( int  in) [inherited]

Assigns an existing socket to this class.
