Detailed Description

This class is a factory for starting off asynchronous accepts on a listen handle. This class forwards all methods to its implementation class.

Once <open> is called, multiple asynchronous <accept>s can started using this class. A ACE_Asynch_Accept::Result will be passed back to the <handler> when the asynchronous accept completes through the <ACE_Handler::handle_accept> callback.

Constructor & Destructor Documentation

Member Function Documentation

int ACE_Asynch_Accept::accept ACE_Message_Block message_block,
size_t  bytes_to_read,
const void *  act = 0,
int  priority = 0,
int  signal_number = ACE_SIGRTMIN,
int  addr_family = AF_INET

This starts off an asynchronous accept. The asynchronous accept call also allows any initial data to be returned to the handler specified to open().

message_block A message block to receive initial data, as well as the local and remote addresses when the connection is made. Since the block receives the addresses regardless of whether or not initial data is available or requested, the message block size must be at least bytes_to_read plus two times the size of the addresses used (IPv4 or IPv6).
bytes_to_read The maximum number of bytes of initial data to read into message_block.
accept_handle The handle that the new connection will be accepted on. If INVALID_HANDLE, a new handle will be created using addr_family.
act Value to be passed in result when operation completes.
priority Priority of the operation. On POSIX4-Unix, this is supported. Works like nice in Unix. Negative values are not allowed. 0 means priority of the operation same as the process priority. 1 means priority of the operation is one less than process. And so forth. On Win32, this argument is ignored.
signal_number The POSIX4 real-time signal number to be used for the operation. Value range is from ACE_SIGRTMIN to ACE_SIGRTMAX. This argument is ignored on non-POSIX4 systems.
addr_family The address family to use if accept_handle is ACE_INVALID_HANDLE and a new handle must be opened. Values are AF_INET and PF_INET6.

ACE_Asynch_Operation_Impl * ACE_Asynch_Accept::implementation void   )  const [virtual]

Return the underlying implementation class.

Implements ACE_Asynch_Operation.

int ACE_Asynch_Accept::open ACE_Handler handler,
const void *  completion_key = 0,
ACE_Proactor proactor = 0

Initializes the factory with information which will be used with each asynchronous call. If (<handle> == ACE_INVALID_HANDLE), <ACE_Handler::handle> will be called on the <handler> to get the correct handle.

Reimplemented from ACE_Asynch_Operation.
