Detailed Description

This class provides concrete implementation for <ACE_Asynch_Write_File> for POSIX platforms where the completion strategy for Proactor is based on AIOCB (AIO Control Blocks).


Constructor & Destructor Documentation

ACE_POSIX_Asynch_Write_File::ACE_POSIX_Asynch_Write_File ( ACE_POSIX_Proactor posix_proactor  ) 

Constructor.

Destructor.


Member Function Documentation

int ACE_POSIX_Asynch_Write_File::write ( ACE_Message_Block message_block,
size_t  bytes_to_write,
const void *  act,
int  priority,
int  signal_number = 0 
) [private, virtual]

This <write> belongs to ACE_POSIX_Asynch_Write_Stream. We have put this here to avoid compiler warnings. We forward this method call to the <ACE_POSIX_Asynch_Write_Stream::write> one.

Implements ACE_Asynch_Write_File_Impl.

int ACE_POSIX_Asynch_Write_File::write ( ACE_Message_Block message_block,
size_t  bytes_to_write,
u_long  offset,
u_long  offset_high,
const void *  act,
int  priority,
int  signal_number = 0 
) [virtual]

This starts off an asynchronous write. Upto bytes_to_write will be written and stored in the message_block. The write will start at offset from the beginning of the file.

Implements ACE_Asynch_Write_File_Impl.
