Detailed Description

Defines the methods in the ACE_SOCK_SEQPACK_Association abstraction.

This adds additional wrapper methods atop the <ACE_SOCK_IO> class.

buf is the buffer to write from or receive into. len is the number of bytes to transfer. The timeout parameter in the following methods indicates how long to blocking trying to transfer data. If timeout == 0, then the call behaves as a normal send/recv call, i.e., for blocking sockets, the call will block until action is possible; for non-blocking sockets, EWOULDBLOCK will be returned if no action is immediately possible. If timeout != 0, the call will wait for data to arrive no longer than the relative time specified in *timeout. The "_n()" I/O methods keep looping until all the data has been transferred. These methods also work for sockets in non-blocking mode i.e., they keep looping on EWOULDBLOCK. timeout is used to make sure we keep making progress, i.e., the same timeout value is used for every I/O operation in the loop and the timeout is not counted down. The return values for the "*_n()" methods match the return values from the non "_n()" methods and are specified as follows:

On partial transfers, i.e., if any data is transferred before timeout/error/EOF, <bytes_transferred> will contain the number of bytes transferred. Methods with <iovec> parameter are I/O vector variants of the I/O operations. Methods with the extra flags argument will always result in <send> getting called. Methods without the extra flags argument will result in <send> getting called on Win32 platforms, and <write> getting called on non-Win32 platforms.

inline

Constructor.

ACE_SOCK_SEQPACK_Association::ACE_SOCK_SEQPACK_Association ( ACE_HANDLE  h)
inline

Constructor (sets the underlying ACE_HANDLE with <h>).

ACE_SOCK_SEQPACK_Association::~ACE_SOCK_SEQPACK_Association ( void  )

Destructor.

Member Function Documentation

int ACE_SOCK_SEQPACK_Association::abort ( void  )

Abort the association according to RFC 2960 9.1 through the API in draft-ietf-tsvwg-sctpsocket-09 7.1.4.

int ACE_SOCK_SEQPACK_Association::close ( void  )

Close down the socket (we need this to make things work correctly on Win32, which requires use to do a <close_writer> before doing the close to avoid losing data).

int ACE_SOCK_SEQPACK_Association::close_reader ( void  )
inline

Close down the reader.

int ACE_SOCK_SEQPACK_Association::close_writer ( void  )
inline

Close down the writer.

void ACE_SOCK_SEQPACK_Association::dump ( void  ) const

Dump the state of an object.

int ACE_SOCK_SEQPACK_Association::get_local_addrs ( ACE_INET_Addr addrs,
size_t &  size 
) const

Return local endpoint addresses in the referenced array of ACE_INET_Addr, which should have the specified size. If the number of local endpoint addresses is less than size, then size will be set to this number. If successful, the method returns 0, otherwise returns -1.

int ACE_SOCK_SEQPACK_Association::get_remote_addrs ( ACE_INET_Addr addrs,
size_t &  size 
) const

Return remote endpoint addresses in the referenced array of ACE_INET_Addr, which should have the specified size. If the number of remote endpoint addresses is less than size, then size will be set to this number. If successful, the method returns 0, otherwise returns -1.

ssize_t ACE_SOCK_SEQPACK_Association::recv_n ( void *  buf,
size_t  len,
int  flags,
const ACE_Time_Value timeout = 0,
size_t *  bytes_transferred = 0 
) const
inline

Try to recv exactly len bytes into buf from the connected socket.

ssize_t ACE_SOCK_SEQPACK_Association::recv_n ( void *  buf,
size_t  len,
const ACE_Time_Value timeout = 0,
size_t *  bytes_transferred = 0 
) const
inline

Try to recv exactly len bytes into buf from the connected socket.

ssize_t ACE_SOCK_SEQPACK_Association::recv_urg ( void *  ptr,
size_t  len = sizeof (char),
const ACE_Time_Value timeout = 0 
) const
inline
ssize_t ACE_SOCK_SEQPACK_Association::recvv_n ( iovec  iov[],
int  iovcnt,
const ACE_Time_Value timeout = 0,
size_t *  bytes_transferred = 0 
) const
inline

Receive an <iovec> of size <iovcnt> from the connected socket.

ssize_t ACE_SOCK_SEQPACK_Association::send_n ( const void *  buf,
size_t  len,
int  flags,
const ACE_Time_Value timeout = 0,
size_t *  bytes_transferred = 0 
) const
inline

Try to send exactly len bytes from buf to the connection socket.

ssize_t ACE_SOCK_SEQPACK_Association::send_n ( const void *  buf,
size_t  len,
const ACE_Time_Value timeout = 0,
size_t *  bytes_transferred = 0 
) const
inline

Try to send exactly len bytes from buf to the connected socket.

ssize_t ACE_SOCK_SEQPACK_Association::send_n ( const ACE_Message_Block message_block,
const ACE_Time_Value timeout = 0,
size_t *  bytes_transferred = 0 
) const
inline

Send all the message_blocks chained through their <next> and <cont> pointers. This call uses the underlying OS gather-write operation to reduce the domain-crossing penalty.

ssize_t ACE_SOCK_SEQPACK_Association::send_urg ( const void *  ptr,
size_t  len = sizeof (char),
const ACE_Time_Value timeout = 0 
) const
inline
ssize_t ACE_SOCK_SEQPACK_Association::sendv_n ( const iovec  iov[],
int  iovcnt,
const ACE_Time_Value timeout = 0,
size_t *  bytes_transferred = 0 
) const
inline

Send an <iovec> of size <iovcnt> to the connected socket.
