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).

Member Function Documentation

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.

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  )

privatevirtual

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.
