Do-nothing constructor.


Member Function Documentation

virtual int ACE_Asynch_Read_Stream_Impl::read ACE_Message_Block message_block,
size_t  bytes_to_read,
const void *  act,
int  priority,
int  signal_number
[pure virtual]
 

This starts off an asynchronous read. Upto <bytes_to_read> will be read and stored in the <message_block>.

Implemented in ACE_Asynch_Read_File_Impl, ACE_POSIX_Asynch_Read_Stream, ACE_POSIX_Asynch_Read_File, ACE_WIN32_Asynch_Read_Stream, and ACE_WIN32_Asynch_Read_File.

virtual int ACE_Asynch_Read_Stream_Impl::readv ACE_Message_Block message_block,
size_t  bytes_to_read,
const void *  act,
int  priority,
int  signal_number
[pure virtual]
 

Same as above but with scatter support, through chaining of composite message blocks using the continuation field.

Implemented in ACE_Asynch_Read_File_Impl, ACE_WIN32_Asynch_Read_Stream, and ACE_WIN32_Asynch_Read_File.
