Detailed Description
Abstract base class for all the concrete implementation classes that provide different implementations for the ACE_Asynch_Write_File.
Constructor & Destructor Documentation
Member Function Documentation
This starts off an asynchronous write. Upto bytes_to_write will be write and stored in the message_block. The write will start at offset from the beginning of the file.
Implemented in ACE_POSIX_Asynch_Write_File.
Same as above but with gather support, through chaining of composite message blocks using the continuation field.
- Note:
- In win32 Each data block payload must be at least the size of a system memory page and must be aligned on a system memory page size boundary
Same as above but with gather support, through chaining of composite message blocks using the continuation field.
Implements ACE_Asynch_Write_Stream_Impl.
