Public Methods

 ACE_WIN32_Asynch_Write_Stream (ACE_WIN32_Proactor *win32_proactor)
 Constructor.

int write (ACE_Message_Block &message_block, u_long bytes_to_write, const void *act, int priority, int signal_number = 0)
 This starts off an asynchronous write. Upto <bytes_to_write> will be written from the <message_block>.

virtual ~ACE_WIN32_Asynch_Write_Stream (void)
 Destructor.

int open (ACE_Handler &handler, ACE_HANDLE handle, const void *completion_key, ACE_Proactor *proactor)
int cancel (void)
ACE_Proactorproactor (void) const
 Return the underlying proactor.


Protected Methods

int shared_write (ACE_WIN32_Asynch_Write_Stream_Result *result)
 This is the method which does the real work and is there so that the ACE_Asynch_Write_File class can use it too.


Detailed Description

This class is a factory for starting off asynchronous writes on a stream.

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

Destructor.


Member Function Documentation

int ACE_WIN32_Asynch_Write_Stream::cancel ( void )
 

This cancels all pending accepts operations that were issued by the calling thread. The function does not cancel asynchronous operations issued by other threads.

Reimplemented from ACE_WIN32_Asynch_Operation.

Reimplemented in ACE_WIN32_Asynch_Write_File.

int ACE_WIN32_Asynch_Write_Stream::open ( ACE_Handler & handler,
ACE_HANDLE handle,
const void * completion_key,
ACE_Proactor * proactor )
 

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

Reimplemented from ACE_WIN32_Asynch_Operation.

Reimplemented in ACE_WIN32_Asynch_Write_File.

ACE_Proactor * ACE_WIN32_Asynch_Write_Stream::proactor ( void ) const
 

Return the underlying proactor.

Reimplemented from ACE_WIN32_Asynch_Operation.

Reimplemented in ACE_WIN32_Asynch_Write_File.

int ACE_WIN32_Asynch_Write_Stream::shared_write ( ACE_WIN32_Asynch_Write_Stream_Result * result ) [protected]
 

This is the method which does the real work and is there so that the ACE_Asynch_Write_File class can use it too.

int ACE_WIN32_Asynch_Write_Stream::write ( ACE_Message_Block & message_block,
u_long bytes_to_write,
const void * act,
int priority,
int signal_number = 0 )
 

This starts off an asynchronous write. Upto <bytes_to_write> will be written from the <message_block>.

Reimplemented in ACE_WIN32_Asynch_Write_File.
