Detailed Description

This class provides implementation for for POSIX platforms.

This class has all the information necessary for the to uniquiely identify the completion of the asynchronous write.

This class differs slightly from <ACE_Asynch_Write_Stream::Result> as it calls back <ACE_Handler::handle_write_file> on the instead of <ACE_Handler::handle_write_stream>. No additional state is required by this class as can store the .

Constructor & Destructor Documentation

ACE_POSIX_Asynch_Write_File_Result::ACE_POSIX_Asynch_Write_File_Result (  const ACE_Handler::Proxy_Ptr &  handler_proxy,
ACE_HANDLE  handle,
ACE_Message_Block &  message_block,
size_t  bytes_to_write,
const void *  act,
u_long  offset,
u_long  offset_high,
ACE_HANDLE  event,
int  priority,
int  signal_number
)  [protected]
 

Constructor is protected since creation is limited to ACE_Asynch_Write_File factory.
