Member Function Documentation

virtual void MNTCPSocket::callback (  MNSelector *  select, int  fd )  [pure virtual]

Reimplemented from MNSocketBase. Implemented in MNTCPServerSocket, MNTCPClientSocket, RTPServerSocket, and RTSPFillBuffer.

virtual Fail MNTCPSocket::connect (  const struct sockaddr_in &  dest  )  [virtual]

Calls transparently the ::connect function. It has been virtualized to provide subclasses the possibility for post-processing, e.g. changing the socket to non-blocking after a successful connect.

virtual Fail MNTCPSocket::connect (  int  port, const char *  hostname )  [virtual]

Calls transparently the ::connect function. It has been virtualized to provide subclasses the possibility for post-processing, e.g. changing the socket to non-blocking after a successful connect. Reimplemented in RTSPFillBuffer.

bool MNTCPSocket::getLocalSockAddr (  struct sockaddr_in &  addr  )

A host with multiple interfaces and INADDR_ANY in the sockaddr_in structure during connect will choose the most appropriate IP address to connect to that host. It is very likely that this address is also the best address to send to the server for connection establishment in the opposite direction. Therefore, this functions makes it possible to ask for this address. It is only valid when the socket is connected. Parameters: addr  An OUT parameter that is supposed to hold the address information for the connected local socket. Returns: True is the address structure has been filled in successfully, false otherwise.

bool MNTCPSocket::getRemoteSockAddr (  struct sockaddr_in &  addr  )

It may be interesting to connect to the same remote interface. If this socket is already connected, you can use this function to get the appropriate structure filled. Parameters: addr  An OUT parameter that will contain the address information of the peer on return, if the return value is true. Returns: True is the address structure has been filled in successfully, false otherwise.

virtual bool MNTCPSocket::isUdp (   )  const [inline, virtual]

Simple function returning false. It is used to figure out what kind of socket is used. This is a TCP class so the function returns false. Returns: Always false since this is a TCP socket class. Implements MNSocket.

int MNTCPSocket::read (  char *  buffer, int  len )

The read call is mapped to the operating system call recv(). The output of recv() is not modified. If the return value is negative, errno holds the details.

void MNTCPSocket::show_buffers (  struct iovec *  iov  )  [protected]

virtual void MNTCPSocket::tcallback (   )  [inline, virtual]

void MNTCPSocket::warn_errors (  int  errval  )

int MNTCPSocket::write (  const char *  buf, int  len )
