Protected Member Functions | |
| int | shared_read (ACE_WIN32_Asynch_Read_Stream_Result *result) |
Once <open> is called, multiple asynchronous <read>s can started using this class. An ACE_Asynch_Read_Stream::Result will be passed back to the <handler> when the asynchronous reads completes through the <ACE_Handler::handle_read_stream> callback.
| ACE_WIN32_Asynch_Read_Stream::ACE_WIN32_Asynch_Read_Stream | ( | ACE_WIN32_Proactor * | win32_proactor | ) |
Constructor.
| ACE_WIN32_Asynch_Read_Stream::~ACE_WIN32_Asynch_Read_Stream | ( | void | ) | [virtual] |
Destructor.
| int ACE_WIN32_Asynch_Read_Stream::cancel | ( | void | ) | [virtual] |
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_Read_File.
| int ACE_WIN32_Asynch_Read_Stream::open | ( | const ACE_Handler::Proxy_Ptr & | handler_proxy, | |
| ACE_HANDLE | handle, | |||
| const void * | completion_key, | |||
| ACE_Proactor * | proactor | |||
| ) | [virtual] |
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_WIN32_Asynch_Operation.
Reimplemented in ACE_WIN32_Asynch_Read_File.
| ACE_Proactor * ACE_WIN32_Asynch_Read_Stream::proactor | ( | void | ) | const [virtual] |
Return the underlying proactor.
Reimplemented from ACE_WIN32_Asynch_Operation.
Reimplemented in ACE_WIN32_Asynch_Read_File.
| int ACE_WIN32_Asynch_Read_Stream::read | ( | ACE_Message_Block & | message_block, | |
| size_t | bytes_to_read, | |||
| const void * | act, | |||
| int | priority, | |||
| int | signal_number = 0 | |||
| ) | [virtual] |
This starts off an asynchronous read. Upto <bytes_to_read> will be read and stored in the <message_block>.
Implements ACE_Asynch_Read_Stream_Impl.
Reimplemented in ACE_WIN32_Asynch_Read_File.
| int ACE_WIN32_Asynch_Read_Stream::readv | ( | ACE_Message_Block & | message_block, | |
| size_t | bytes_to_read, | |||
| const void * | act, | |||
| int | priority, | |||
| int | signal_number = 0 | |||
| ) | [virtual] |
Same as above but with scatter support, through chaining of composite message blocks using the continuation field.
Implements ACE_Asynch_Read_Stream_Impl.
Reimplemented in ACE_WIN32_Asynch_Read_File.
| int ACE_WIN32_Asynch_Read_Stream::shared_read | ( | ACE_WIN32_Asynch_Read_Stream_Result * | result | ) | [protected] |
This is the method which does the real work and is there so that the ACE_Asynch_Read_File class can use it too.
