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.
